function Export-DbatoolsConfig
{
<#
    .SYNOPSIS
        Exports configuration items to a Json file.
    
    .DESCRIPTION
        Exports configuration items to a Json file.
    
    .PARAMETER FullName
        Select the configuration objects to export by filtering by their full name.
    
    .PARAMETER Module
        Select the configuration objects to export by filtering by their module name.
    
    .PARAMETER Name
        Select the configuration objects to export by filtering by their name.
    
    .PARAMETER Config
        The configuration object(s) to export.
        Returned by Get-DbatoolsConfig.
    
    .PARAMETER ModuleName
        Exports all configuration pertinent to a module to a predefined path.
        Exported configuration items include all settings marked as 'ModuleExport' that have been changed from the default value.
    
    .PARAMETER ModuleVersion
        The configuration version of the module-settings to write.
    
    .PARAMETER Scope
        Which predefined path to write module specific settings to.
        Only file scopes are considered.
        By default it writes to the suer profile.
    
    .PARAMETER OutPath
        The path (filename included) to export to.
        Will fail if the folder does not exist, will overwrite the file if it exists.
    
    .PARAMETER SkipUnchanged
        If set, configuration objects whose value was not changed from its original value will not be exported.
        (Note: Settings that were updated with the same value as the original default will still be considered changed)
    
    .PARAMETER EnableException
        This parameters disables user-friendly warnings and enables the throwing of exceptions.
        This is less user friendly, but allows catching exceptions in calling scripts.
    
    .EXAMPLE
        PS C:\> Get-DbatoolsConfig | Export-DbatoolsConfig -OutPath '~/export.json'
        
        Exports all current settings to json.
    
    .EXAMPLE
        Export-DbatoolsConfig -Module message -OutPath '~/export.json' -SkipUnchanged
        
        Exports all settings of the module 'message' that are no longer the original default values to json.

    .SYNOPSIS
        Returns the configuration value stored under the specified name.

    .DESCRIPTION
        Returns the configuration value stored under the specified name.
        It requires the full name (<Module>.<Name>) and is usually only called by functions.

    .PARAMETER FullName
        The full name (<Module>.<Name>) of the configured value to return.

    .PARAMETER Fallback
        A fallback value to use, if no value was registered to a specific configuration element.
        This basically is a default value that only applies on a "per call" basis, rather than a system-wide default.

    .PARAMETER NotNull
        By default, this function returns null if one tries to retrieve the value from either a Configuration that does not exist or a Configuration whose value was set to null.
        However, sometimes it may be important that some value was returned.
        By specifying this parameter, the function will throw an error if no value was found at all.

        It also can be used to generate a registry template, which can then be used to create policies.
    
    .PARAMETER Config
        The configuration object to write to registry.
        Can be retrieved using Get-DbatoolsConfig.
    
    .PARAMETER FullName
        The full name of the setting to be written to registry.
    
    .PARAMETER Module
        The name of the module, whose settings should be written to registry.
    
    .PARAMETER Name
        Default: "*"
        Used in conjunction with the -Module parameter to restrict the number of configuration items written to registry.
    
    .PARAMETER Scope
        Default: UserDefault
        Who will be affected by this export how? Current user or all? Default setting or enforced?
        Legal values: UserDefault, UserMandatory, SystemDefault, SystemMandatory
    
    .PARAMETER EnableException
        This parameters disables user-friendly warnings and enables the throwing of exceptions.
        This is less user friendly, but allows catching exceptions in calling scripts.
    
    .EXAMPLE
        PS C:\> Get-DbatoolsConfig message.style.* | Register-DbatoolsConfig
    
        Retrieves all configuration items that that start with message.style. and registers them in registry for the current user.
    
    .EXAMPLE
        PS C:\> Register-DbatoolsConfig -FullName "message.consoleoutput.disable" -Scope SystemDefault
    
        Retrieves the configuration item "message.consoleoutput.disable" and registers it in registry as the default setting for all users on this machine.
    
    .EXAMPLE
        PS C:\> Register-DbatoolsConfig -Module Message -Scope SystemMandatory
    
        Retrieves all configuration items of the module Message, then registers them in registry to enforce them for all users on the current system.

<#
    .SYNOPSIS
        Reverts a configuration item to its default value.
    
    .DESCRIPTION
        This command can be used to revert a configuration item to the value it was initialized with.
        Generally, this amounts to reverting it to its default value.
        
        In order for a reset to be possible, two conditions must be met:
        - The setting must have been initialized.
        - The setting cannot have been enforced by policy.
    
    .PARAMETER ConfigurationItem
        A configuration object as returned by Get-DbatoolsConfig.
    
    .PARAMETER FullName
        The full name of the setting to reset, offering the maximum of precision.
    
    .PARAMETER Module
        The name of the module, from which configurations should be reset.
        Used in conjunction with the -Name parameter to filter a specific set of items.
    
    .PARAMETER Name
        Used in conjunction with the -Module parameter to select which settings to reset using wildcard comparison.
    
    .PARAMETER EnableException
        This parameters disables user-friendly warnings and enables the throwing of exceptions.
        This is less user friendly, but allows catching exceptions in calling scripts.
    
    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.
    
    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.
    
    .EXAMPLE
        PS C:\> Reset-DbatoolsConfig -Module MyModule
    
        Resets all configuration items of the MyModule to default.

<#
    .SYNOPSIS
        Removes registered configuration settings.
    
    .DESCRIPTION
        Removes registered configuration settings.
        This function can be used to remove settings that have been persisted for either user or computer.
    
        Note: This command has no effect on configuration setings currently in memory.
    
    .PARAMETER ConfigurationItem
        A configuration object as returned by Get-DbatoolsConfig.
    
    .PARAMETER FullName
        The full name of the configuration setting to purge.
    
    .PARAMETER Module
        The module, amongst which settings should be unregistered.
    
    .PARAMETER Name
        The name of the setting to unregister.
        For use together with the module parameter, to limit the amount of settings that are unregistered.
    
    .PARAMETER Scope
        Settings can be set to either default or enforced, for user or the entire computer.
        By default, only DefaultSettings for the user are unregistered.
        Use this parameter to choose the actual scope for the command to process.
    
    .EXAMPLE
        PS C:\> Get-DbatoolsConfig | Unregister-DbatoolsConfig
    
        Completely removes all registered configurations currently loaded in memory.
        In most cases, this will mean removing all registered configurations.
    
    .EXAMPLE
        PS C:\> Unregister-DbatoolsConfig -Scope SystemDefault -FullName 'MyModule.Path.DefaultExport'
    
        Unregisters the setting 'MyModule.Path.DefaultExport' from the list of computer-wide defaults.
        Note: Changing system wide settings requires running the console with elevation.
    
    .EXAMPLE
        PS C:\> Unregister-DbatoolsConfig -Module MyModule
    
        Unregisters all configuration settings for the module MyModule.

    <#
    .SYNOPSIS
        Adds a database to an availability group on a SQL Server instance.

    .DESCRIPTION
        Adds a database to an availability group on a SQL Server instance.

        Before joining the replica databases to the availablity group, the databases will be initialized with automatic seeding or full/log backup.

   .PARAMETER SqlInstance
        The target SQL Server instance or instances. Server version must be SQL Server version 2012 or higher.

        This should be the primary replica.

    .PARAMETER SqlCredential
        Login to the SqlInstance instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Database
        The database or databases to add.

    .PARAMETER AvailabilityGroup
        The availability group where the databases will be added.

    .PARAMETER Secondary
        Not required - the command will figure this out. But if you'd like to be explicit about replicas, this will help.

    .PARAMETER SecondarySqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER InputObject
        Enables piping from Get-DbaDatabase, Get-DbaDbSharePoint and more.

    .PARAMETER SeedingMode
        Specifies how the secondary replica will be initially seeded.

        Automatic enables direct seeding. This method will seed the secondary replica over the network. This method does not require you to backup and restore a copy of the primary database on the replica.

        Manual requires you to create a backup of the database on the primary replica and manually restore that backup on the secondary replica.

        If not specified, the setting from the availability group replica will be used. Otherwise the setting will be updated.

    .PARAMETER SharedPath
        The network share where the backups will be backed up and restored from.

        Each SQL Server service account must have access to this share.

        NOTE: If a backup / restore is performed, the backups will be left in tact on the network share.

    .PARAMETER UseLastBackup
        Use the last full backup of database.

    .PARAMETER WhatIf
        Shows what would happen if the command were to run. No actions are actually performed.

    .PARAMETER Confirm
        Prompts you for confirmation before executing any changing operations within the command.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .SYNOPSIS
        Adds a replica to an availability group on a SQL Server instance.

    .DESCRIPTION
        Adds a replica to an availability group on a SQL Server instance.

        Automatically creates a database mirroring endpoint if required.

   .PARAMETER SqlInstance
        The target SQL Server instance or instances. Server version must be SQL Server version 2012 or higher.

    .PARAMETER SqlCredential
        Login to the SqlInstance instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Name
        The name of the replica. Defaults to the SQL Server instance name.

    .PARAMETER AvailabilityMode
        Sets the availability mode of the availability group replica. Options are: AsynchronousCommit and SynchronousCommit. SynchronousCommit is default.

    .PARAMETER FailoverMode
        Sets the failover mode of the availability group replica. Options are Automatic and Manual. Automatic is default.

    .PARAMETER BackupPriority
        Sets the backup priority availability group replica. Default is 50.

    .PARAMETER Endpoint
        By default, this command will attempt to find a DatabaseMirror endpoint. If one does not exist, it will create it.

        If an endpoint must be created, the name "hadr_endpoint" will be used. If an alternative is preferred, use Endpoint.

    .PARAMETER Passthru
        Don't create the replica, just pass thru an object that can be further customized before creation.

    .PARAMETER InputObject
        Enables piping from Get-DbaAvailabilityGroup.

    .PARAMETER ConnectionModeInPrimaryRole
        Specifies the connection intent modes of an Availability Replica in primary role. AllowAllConnections by default.

    .PARAMETER ConnectionModeInSecondaryRole
        Specifies the connection modes of an Availability Replica in secondary role. AllowAllConnections by default.

    .PARAMETER ReadonlyRoutingConnectionUrl
        Sets the read only routing connection url for the availability replica.

    .PARAMETER SeedingMode
        Specifies how the secondary replica will be initially seeded.

        Automatic enables direct seeding. This method will seed the secondary replica over the network. This method does not require you to backup and restore a copy of the primary database on the replica.

        Manual requires you to create a backup of the database on the primary replica and manually restore that backup on the secondary replica.

    .PARAMETER Certificate
        Specifies that the endpoint is to authenticate the connection using the certificate specified by certificate_name to establish identity for authorization.

        The far endpoint must have a certificate with the public key matching the private key of the specified certificate.

    .PARAMETER WhatIf
        Shows what would happen if the command were to run. No actions are actually performed.

    .PARAMETER Confirm
        Prompts you for confirmation before executing any changing operations within the command.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .PARAMETER SqlInstance
        The target SQL Server instance

    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER ServerName
        Server Name is the actual SQL instance name (labeled Server Name)

    .PARAMETER Name
        Name is basically the nickname in SSMS CMS interface (labeled Registered Server Name)

    .PARAMETER Description
        Adds a description for the registered server

    .PARAMETER Group
        Adds the registered server to a specific group.

    .PARAMETER InputObject
        Allows the piping of a registered server group

    .PARAMETER WhatIf
        Shows what would happen if the command were to run. No actions are actually performed.

    .PARAMETER Confirm
        Prompts you for confirmation before executing any changing operations within the command.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.

        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.

function Add-DbaComputerCertificate {
    <#
    .SYNOPSIS
        Adds a computer certificate - useful for older systems.

    .DESCRIPTION
        Adds a computer certificate from a local or remote computer.

    .PARAMETER ComputerName
        The target SQL Server instance or instances. Defaults to localhost.

    .PARAMETER Credential
        Allows you to login to $ComputerName using alternative credentials.

    .PARAMETER SecurePassword
        The password for the certificate, if it is password protected.

    .PARAMETER Certificate
        The target certificate object.

    .PARAMETER Path
        The local path to the target certificate object.

    .PARAMETER Store
        Certificate store. Default is LocalMachine.

    .PARAMETER Folder
        Certificate folder. Default is My (Personal).

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

function Backup-DbaDatabase {
    <#
    .SYNOPSIS
        Backup one or more SQL Sever databases from a single SQL Server SqlInstance.

    .DESCRIPTION
        Performs a backup of a specified type of 1 or more databases on a single SQL Server Instance. These backups may be Full, Differential or Transaction log backups.

    .PARAMETER SqlInstance
        The SQL Server instance hosting the databases to be backed up.

    .PARAMETER SqlCredential
        Credentials to connect to the SQL Server instance if the calling user does not have permission.

    .PARAMETER Database
        The database(s) to process. This list is auto-populated from the server. If unspecified, all databases will be processed.

    .PARAMETER ExcludeDatabase
        The database(s) to exclude. This list is auto-populated from the server.

    .PARAMETER BackupFileName
        The name of the file to backup to. This is only accepted for single database backups.
        If no name is specified then the backup files will be named DatabaseName_yyyyMMddHHmm (i.e. "Database1_201714022131") with the appropriate extension.

        If the same name is used repeatedly, SQL Server will add backups to the same file at an incrementing position.

        SQL Server needs permissions to write to the specified location. Path names are based on the SQL Server (C:\ is the C drive on the SQL Server, not the machine running the script).

        Passing in NUL as the BackupFileName will backup to the NUL: device

    .PARAMETER TimeStampFormat
        By default the command timestamps backups using the format yyyyMMddHHmm. Using this parameter this can be overridden. The timestamp format should be defined using the Get-Date formats, illegal formats will cause an error to be thrown

    .PARAMETER BackupDirectory
        Path in which to place the backup files. If not specified, the backups will be placed in the default backup location for SqlInstance.
        If multiple paths are specified, the backups will be striped across these locations. This will overwrite the FileCount option.

        If the path does not exist, Sql Server will attempt to create it. Folders are created by the Sql Instance, and checks will be made for write permissions.

        File Names with be suffixed with x-of-y to enable identifying striped sets, where y is the number of files in the set and x ranges from 1 to y.

    .PARAMETER ReplaceInName
        If this switch is set, the following list of strings will be replaced in the BackupFileName and BackupDirectory strings:
            instancename - will be replaced with the instance Name
            servername - will be replaced with the server name
            dbname - will be replaced with the database name
            timestamp - will be replaced with the timestamp (either the default, or the format provided)
            backuptype - will be replaced with Full, Log or Differential as appropriate

    .PARAMETER CopyOnly
        If this switch is enabled, CopyOnly backups will be taken. By default function performs a normal backup, these backups interfere with the restore chain of the database. CopyOnly backups will not interfere with the restore chain of the database.

        For more details please refer to this MSDN article - https://msdn.microsoft.com/en-us/library/ms191495.aspx

    .PARAMETER Type
        The type of SQL Server backup to perform. Accepted values are "Full", "Log", "Differential", "Diff", "Database"

    .PARAMETER FileCount
        This is the number of striped copies of the backups you wish to create.    This value is overwritten if you specify multiple Backup Directories.

    .PARAMETER CreateFolder
        If this switch is enabled, each database will be backed up into a separate folder on each of the paths specified by BackupDirectory.

    .PARAMETER CompressBackup
        If this switch is enabled, the function will try to perform a compressed backup if supported by the version and edition of SQL Server. Otherwise, this function will use the server(s) default setting for compression.

    .PARAMETER MaxTransferSize
        Sets the size of the unit of transfer. Values must be a multiple of 64kb.

    .PARAMETER Blocksize
        Specifies the block size to use. Must be one of 0.5KB, 1KB, 2KB, 4KB, 8KB, 16KB, 32KB or 64KB. This can be specified in bytes.
        Refer to https://msdn.microsoft.com/en-us/library/ms178615.aspx for more detail

    .PARAMETER BufferCount
        Number of I/O buffers to use to perform the operation.
        Refer to https://msdn.microsoft.com/en-us/library/ms178615.aspx for more detail

    .PARAMETER Checksum
        If this switch is enabled, the backup checksum will be calculated.

    .PARAMETER Verify
        If this switch is enabled, the backup will be verified by running a RESTORE VERIFYONLY against the SqlInstance

    .PARAMETER WithFormat
        Formats the media as the first step of the backup operation. NOTE: This will set Initialize and SkipTapeHeader to $true.

    .PARAMETER Initialize
        Initializes the media as part of the backup operation.

    .PARAMETER SkipTapeHeader
        Initializes the media as part of the backup operation.

    .PARAMETER InputObject
        Internal parameter

    .PARAMETER AzureBaseUrl
        The URL to the base container of an Azure Storage account to write backups to.

        If specified, the only other parameters than can be used are "CopyOnly", "Type", "CompressBackup", "Checksum", "Verify", "AzureCredential", "CreateFolder".

    .PARAMETER AzureCredential
        The name of the credential on the SQL instance that can write to the AzureBaseUrl, only needed if using Storage access keys
        If using SAS credentials, the command will look for a credential with a name matching the AzureBaseUrl

    .PARAMETER NoRecovery
        This is passed in to perform a tail log backup if needed

    .PARAMETER BuildPath
        By default this command will not attempt to create missing paths, this switch will change the behaviour so that it will

    .PARAMETER IgnoreFileChecks
        This switch stops the function from checking for the validity of paths. This can be useful if SQL Server only has read access to the backup area.
        Note, that as we cannot check the path you may well end up with errors.

    .PARAMETER OutputScriptOnly
        Switch causes only the T-SQL script for the backup to be generated. Will not create any paths if they do not exist

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .EXAMPLE
        PS C:\> Backup-DbaDatabase -SqlInstance Server1 -Database HR, Finance

        This will perform a full database backup on the databases HR and Finance on SQL Server Instance Server1 to Server1 default backup directory.

    .EXAMPLE
        PS C:\> Backup-DbaDatabase -SqlInstance sql2016 -BackupDirectory C:\temp -Database AdventureWorks2014 -Type Full

        Backs up AdventureWorks2014 to sql2016 C:\temp folder.

    .EXAMPLE
        PS C:\> Backup-DbaDatabase -SqlInstance sql2016 -AzureBaseUrl https://dbatoolsaz.blob.core.windows.net/azbackups/ -AzureCredential dbatoolscred -Type Full -CreateFolder

        Performs a full backup of all databases on the sql2016 instance to their own containers under the https://dbatoolsaz.blob.core.windows.net/azbackups/ container on Azure blog storage using the sql credential "dbatoolscred" registered on the sql2016 instance.

    .EXAMPLE
        PS C:\> Backup-DbaDatabase -SqlInstance sql2016 -AzureBaseUrl https://dbatoolsaz.blob.core.windows.net/azbackups/  -Type Full

        Performs a full backup of all databases on the sql2016 instance to the https://dbatoolsaz.blob.core.windows.net/azbackups/ container on Azure blog storage using the Shared Access Signature sql credential "https://dbatoolsaz.blob.core.windows.net/azbackups" registered on the sql2016 instance.

    .EXAMPLE
        PS C:\> Backup-Dbadatabase -SqlInstance Server1\Prod -Database db1 -BackupDirectory \\filestore\backups\servername\instancename\dbname\backuptype -Type Full -ReplaceInName

        Performs a full backup of db1 into the folder \\filestore\backups\server1\prod\db1

    .EXAMPLE
        PS C:\> Backup-Dbadatabase -SqlInstance Server1\Prod -BackupDirectory \\filestore\backups\servername\instancename\dbname\backuptype -BackupFileName dbname-backuptype-timestamp.trn -Type Log -ReplaceInName

        Performs a log backup for every database. For the database db1 this would results in backup files in \\filestore\backups\server1\prod\db1\Log\db1-log-31102018.trn

    .EXAMPLE
        PS C:\> Backup-DbaDatabase -SqlInstance Sql2017 -Database master -BackupFileName NUL

        Performs a backup of master, but sends the output to the NUL device (ie; throws it away)

    .SYNOPSIS
        Exports database certificates from SQL Server using SMO.

    .DESCRIPTION
        Exports database certificates from SQL Server using SMO and outputs the .cer and .pvk files.

    .PARAMETER SqlInstance
        The target SQL Server instance or instances. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances.

    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Certificate
        Exports certificate that matches the name(s).

    .PARAMETER Database
        Exports the encryptor for specific database(s).

    .PARAMETER ExcludeDatabase
        Database(s) to skip when exporting encryptors.

    .PARAMETER EncryptionPassword
        A string value that specifies the system path to encrypt the private key.

    .PARAMETER DecryptionPassword
        A string value that specifies the system path to decrypt the private key.

    .PARAMETER Path
        The path to output the files to. The path is relative to the SQL Server itself. If no path is specified, the default data directory will be used.

    .PARAMETER Suffix
        The suffix of the filename of the exported certificate.

    .PARAMETER InputObject
        Enables piping from Get-DbaDbCertificate

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .EXAMPLE
        PS C:\> Backup-DbaDbCertificate -SqlInstance Server1

        Exports all the certificates on the specified SQL Server to the default data path for the instance.

    .EXAMPLE
        PS C:\> $cred = Get-Credential sqladmin
        PS C:\> Backup-DbaDbCertificate -SqlInstance Server1 -SqlCredential $cred

        Connects using sqladmin credential and exports all the certificates on the specified SQL Server to the default data path for the instance.

    .EXAMPLE
        PS C:\> Backup-DbaDbCertificate -SqlInstance Server1 -Certificate Certificate1

        Exports only the certificate named Certificate1 on the specified SQL Server to the default data path for the instance.

    .EXAMPLE
        PS C:\> Backup-DbaDbCertificate -SqlInstance Server1 -Database AdventureWorks

        Exports only the certificates for AdventureWorks on the specified SQL Server to the default data path for the instance.

    .EXAMPLE
        PS C:\> Backup-DbaDbCertificate -SqlInstance Server1 -ExcludeDatabase AdventureWorks

        Exports all certificates except those for AdventureWorks on the specified SQL Server to the default data path for the instance.

    .EXAMPLE
        PS C:\> Backup-DbaDbCertificate -SqlInstance Server1 -Path \\Server1\Certificates -EncryptionPassword (ConvertTo-SecureString -force -AsPlainText GoodPass1234!!)

        Exports all the certificates and private keys on the specified SQL Server.

    .EXAMPLE
        PS C:\> $EncryptionPassword = ConvertTo-SecureString -AsPlainText "GoodPass1234!!" -force
        PS C:\> $DecryptionPassword = ConvertTo-SecureString -AsPlainText "Password4567!!" -force
        PS C:\> Backup-DbaDbCertificate -SqlInstance Server1 -EncryptionPassword $EncryptionPassword -DecryptionPassword $DecryptionPassword

        Exports all the certificates on the specified SQL Server using the supplied DecryptionPassword, since an EncryptionPassword is specified private keys are also exported.

    .EXAMPLE
        PS C:\> Backup-DbaDbCertificate -SqlInstance Server1 -Path \\Server1\Certificates

        Exports all certificates on the specified SQL Server to the specified path.

    .EXAMPLE
        PS C:\> Backup-DbaDbCertificate -SqlInstance Server1 -Suffix DbaTools

        Exports all certificates on the specified SQL Server to the specified path, appends DbaTools to the end of the filenames.

    .EXAMPLE
        PS C:\> Get-DbaDbCertificate -SqlInstance sql2016 | Backup-DbaDbCertificate

        Exports all certificates found on sql2016 to the default data directory.

function Backup-DbaDbMasterKey {
    <#
    .SYNOPSIS
        Backs up specified database master key.

    .DESCRIPTION
        Backs up specified database master key.

    .PARAMETER SqlInstance
        The target SQL Server instance or instances.

    .PARAMETER SqlCredential
        Allows you to login to SQL Server using alternative credentials.

    .PARAMETER Database
        Backup master key from specific database(s).

    .PARAMETER ExcludeDatabase
        The database(s) to exclude - this list is auto-populated from the server.

    .PARAMETER Path
        The directory to export the key. If no path is specified, the default backup directory for the instance will be used.

    .PARAMETER Credential
        Pass a credential object for the password

    .PARAMETER SecurePassword
        The password to encrypt the exported key. This must be a SecureString.

    .PARAMETER InputObject
        Database object piped in from Get-DbaDatabase

    .PARAMETER WhatIf
        Shows what would happen if the command were to run. No actions are actually performed.

    .PARAMETER Confirm
        Prompts you for confirmation before executing any changing operations within the command.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .SYNOPSIS
        Clears wait statistics

    .DESCRIPTION
        Reset the aggregated statistics - basically just executes DBCC SQLPERF (N'sys.dm_os_wait_stats', CLEAR)

    .PARAMETER SqlInstance
        The target SQL Server instance or instances.

    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

function Connect-DbaInstance {
    <#
    .SYNOPSIS
        Creates a robust SMO SQL Server object.

    .DESCRIPTION
        This command is robust because it initializes properties that do not cause enumeration by default. It also supports both Windows and SQL Server authentication methods, and detects which to use based upon the provided credentials.

        By default, this command also sets the connection's ApplicationName property  to "dbatools PowerShell module - dbatools.io - custom connection". If you're doing anything that requires profiling, you can look for this client name.

        Alternatively, you can pass in whichever client name you'd like using the -ClientName parameter. There are a ton of other parameters for you to explore as well.

        See https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.connectionstring.aspx
        and https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnectionstringbuilder.aspx,
        and https://msdn.microsoft.com/en-us/library/system.data.sqlclient.sqlconnection.aspx

        To execute SQL commands, you can use $server.ConnectionContext.ExecuteReader($sql) or $server.Databases['master'].ExecuteNonQuery($sql)

    .PARAMETER SqlInstance
        The target SQL Server instance or instances. This can be a collection and receive pipeline input to allow the function to be executed against multiple SQL Server instances.

    .PARAMETER SqlCredential
        Credential object used to connect to the SQL Server Instance as a different user. This can be a Windows or SQL Server account. Windows users are determined by the existence of a backslash, so if you are intending to use an alternative Windows connection instead of a SQL login, ensure it contains a backslash.

    .PARAMETER Database
        The database(s) to process. This list is auto-populated from the server.

    .PARAMETER AccessToken
        Gets or sets the access token for the connection.

    .PARAMETER AppendConnectionString
        Appends to the current connection string. Note that you cannot pass authentication information using this method. Use -SqlInstance and optionally -SqlCredential to set authentication information.

    .PARAMETER ApplicationIntent
        Declares the application workload type when connecting to a server.

        Valid values are "ReadOnly" and "ReadWrite".

    .PARAMETER BatchSeparator
        A string to separate groups of SQL statements being executed. By default, this is "GO".

    .PARAMETER ClientName
        By default, this command sets the client's ApplicationName property to "dbatools PowerShell module - dbatools.io - custom connection" if you're doing anything that requires profiling, you can look for this client name. Using -ClientName allows you to set your own custom client application name.

    .PARAMETER ConnectTimeout
        The length of time (in seconds) to wait for a connection to the server before terminating the attempt and generating an error.

        Valid values are integers between 0 and 2147483647.

        When opening a connection to a Azure SQL Database, set the connection timeout to 30 seconds.

    .PARAMETER EncryptConnection
        If this switch is enabled, SQL Server uses SSL encryption for all data sent between the client and server if the server has a certificate installed.

        For more information, see Connection String Syntax. https://docs.microsoft.com/en-us/dotnet/framework/data/adonet/connection-string-syntax

        Beginning in .NET Framework 4.5, when TrustServerCertificate is false and Encrypt is true, the server name (or IP address) in a SQL Server SSL certificate must exactly match the server name (or IP address) specified in the connection string. Otherwise, the connection attempt will fail. For information about support for certificates whose subject starts with a wildcard character (*), see Accepted wildcards used by server certificates for server authentication. https://support.microsoft.com/en-us/help/258858/accepted-wildcards-used-by-server-certificates-for-server-authenticati

    .PARAMETER FailoverPartner
        The name of the failover partner server where database mirroring is configured.

        If the value of this key is "" (an empty string), then Initial Catalog must be present in the connection string, and its value must not be "".

        The server name can be 128 characters or less.

        If you specify a failover partner but the failover partner server is not configured for database mirroring and the primary server (specified with the Server keyword) is not available, then the connection will fail.

        If you specify a failover partner and the primary server is not configured for database mirroring, the connection to the primary server (specified with the Server keyword) will succeed if the primary server is available.

    .PARAMETER LockTimeout
        Sets the time in seconds required for the connection to time out when the current transaction is locked.

    .PARAMETER MaxPoolSize
        Sets the maximum number of connections allowed in the connection pool for this specific connection string.

    .PARAMETER MinPoolSize
        Sets the minimum number of connections allowed in the connection pool for this specific connection string.

    .PARAMETER MultipleActiveResultSets
        If this switch is enabled, an application can maintain multiple active result sets (MARS).

        If this switch is not enabled, an application must process or cancel all result sets from one batch before it can execute any other batch on that connection.

    .PARAMETER MultiSubnetFailover
        If this switch is enabled, and your application is connecting to an AlwaysOn availability group (AG) on different subnets, detection of and connection to the currently active server will be faster. For more information about SqlClient support for Always On Availability Groups, see https://docs.microsoft.com/en-us/dotnet/framework/data/adonet/sql/sqlclient-support-for-high-availability-disaster-recovery

    .PARAMETER NetworkProtocol
        Explicitly sets the network protocol used to connect to the server.

        Valid values are "TcpIp","NamedPipes","Multiprotocol","AppleTalk","BanyanVines","Via","SharedMemory" and "NWLinkIpxSpx"

    .PARAMETER NonPooledConnection
        If this switch is enabled, a non-pooled connection will be requested.

    .PARAMETER PacketSize
        Sets the size in bytes of the network packets used to communicate with an instance of SQL Server. Must match at server.

    .PARAMETER PooledConnectionLifetime
        When a connection is returned to the pool, its creation time is compared with the current time and the connection is destroyed if that time span (in seconds) exceeds the value specified by Connection Lifetime. This is useful in clustered configurations to force load balancing between a running server and a server just brought online.

        A value of zero (0) causes pooled connections to have the maximum connection timeout.

    .PARAMETER SqlExecutionModes
        The SqlExecutionModes enumeration contains values that are used to specify whether the commands sent to the referenced connection to the server are executed immediately or saved in a buffer.

        Valid values include "CaptureSql", "ExecuteAndCaptureSql" and "ExecuteSql".

    .PARAMETER StatementTimeout
        Sets the number of seconds a statement is given to run before failing with a timeout error.

    .PARAMETER TrustServerCertificate
        When this switch is enabled, the channel will be encrypted while bypassing walking the certificate chain to validate trust.

    .PARAMETER WorkstationId
        Sets the name of the workstation connecting to SQL Server.

    .PARAMETER SqlConnectionOnly
        Instead of returning a rich SMO server object, this command will only return a SqlConnection object when setting this switch.

    .PARAMETER DisableException
        By default in most of our commands, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.

        This command, however, gifts you  with "sea of red" exceptions, by default, because it is useful for advanced scripting.

        Using this switch turns our "nice by default" feature on which makes errors into pretty warnings.

    .EXAMPLE
        PS C:\> $sqlcred = Get-Credential sqladmin
        PS C:\> $server = Connect-DbaInstance -SqlInstance sql2014 -SqlCredential $sqlcred

        Login to sql2014 as SQL login sqladmin.

    .EXAMPLE
        PS C:\> $server = Connect-DbaInstance -SqlInstance sql2014 -ClientName "my connection"

        Creates an SMO Server object that connects using Windows Authentication and uses the client name "my connection". So when you open up profiler or use extended events, you can search for "my connection".

    .EXAMPLE
        PS C:\> $server = Connect-DbaInstance -SqlInstance sql2014 -AppendConnectionString "Packet Size=4096;AttachDbFilename=C:\MyFolder\MyDataFile.mdf;User Instance=true;"

        Creates an SMO Server object that connects to sql2014 using Windows Authentication, then it sets the packet size (this can also be done via -PacketSize) and other connection attributes.

    .EXAMPLE
        PS C:\> $server = Connect-DbaInstance -SqlInstance sql2014 -NetworkProtocol TcpIp -MultiSubnetFailover

        Creates an SMO Server object that connects using Windows Authentication that uses TCP/IP and has MultiSubnetFailover enabled.

    .EXAMPLE
        PS C:\> $server = Connect-DbaInstance sql2016 -ApplicationIntent ReadOnly

        Connects with ReadOnly ApplicationIntent.

    .SYNOPSIS
        Creates a DataTable for an object.

    .DESCRIPTION
        Creates a DataTable based on an object's properties. This allows you to easily write to SQL Server tables.

        Thanks to Chad Miller, this is based on his script. https://gallery.technet.microsoft.com/scriptcenter/4208a159-a52e-4b99-83d4-8048468d29dd

        If the attempt to convert to data table fails, try the -Raw parameter for less accurate datatype detection.

    .PARAMETER InputObject
        The object to transform into a DataTable.

    .PARAMETER TimeSpanType
        Specifies the type to convert TimeSpan objects into. Default is 'TotalMilliseconds'. Valid options are: 'Ticks', 'TotalDays', 'TotalHours', 'TotalMinutes', 'TotalSeconds', 'TotalMilliseconds', and 'String'.

    .PARAMETER SizeType
        Specifies the type to convert DbaSize objects to. Default is 'Int64'. Valid options are 'Int32', 'Int64', and 'String'.

    .PARAMETER IgnoreNull
        If this switch is enabled, objects with null values will be ignored (empty rows will be added by default).

    .PARAMETER Raw
        If this switch is enabled, the DataTable will be created with strings. No attempt will be made to parse/determine data types.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

function ConvertTo-DbaTimeline {
    <#
    .SYNOPSIS
        Converts InputObject to a html timeline using Google Chart

    .DESCRIPTION
        This function accepts input as pipeline from the following dbatools functions:
        Get-DbaAgentJobHistory
        Get-DbaBackupHistory
        (more to come...)
        And generates Bootstrap based, HTML file with Google Chart Timeline

    .PARAMETER InputObject

        Pipe input, must an output from the above functions.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

function ConvertTo-DbaXESession {
    <#
    .SYNOPSIS
        Uses a slightly modified version of sp_SQLskills_ConvertTraceToExtendedEvents.sql to convert Traces to Extended Events.

    .DESCRIPTION
        Uses a slightly modified version of sp_SQLskills_ConvertTraceToExtendedEvents.sql to convert Traces to Extended Events.

        T-SQL code by: Jonathan M. Kehayias, SQLskills.com. T-SQL can be found in this module directory and at
        https://www.sqlskills.com/blogs/jonathan/converting-sql-trace-to-extended-events-in-sql-server-2012/

    .PARAMETER InputObject
        Specifies a Trace object output by Get-DbaTrace.

    .PARAMETER Name
        The name of the Trace to convert. If the name exists, characters will be appended to it.

    .PARAMETER OutputScriptOnly
        Outputs the T-SQL script to create the XE session and does not execute it.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .EXAMPLE
        PS C:\> Get-DbaTrace -SqlInstance sql2017, sql2012 | Where Id -eq 2 | ConvertTo-DbaXESession -Name 'Test'

        Converts Trace with ID 2 to a Session named Test on SQL Server instances named sql2017 and sql2012 and creates the Session on each respective server.

    .EXAMPLE
        PS C:\> Get-DbaTrace -SqlInstance sql2014 | Out-GridView -PassThru | ConvertTo-DbaXESession -Name 'Test' | Start-DbaXESession

        Converts selected traces on sql2014 to sessions, creates the session, and starts it.

    .EXAMPLE
        PS C:\> Get-DbaTrace -SqlInstance sql2014 | Where Id -eq 1 | ConvertTo-DbaXESession -Name 'Test' -OutputScriptOnly

        Converts trace ID 1 on sql2014 to an Extended Event and outputs the resulting T-SQL.

function Copy-DbaAgentAlert {
    <#
    .SYNOPSIS
        Copy-DbaAgentAlert migrates alerts from one SQL Server to another.

    .DESCRIPTION
        By default, all alerts are copied. The -Alert parameter is auto-populated for command-line completion and can be used to copy only specific alerts.

        If the alert already exists on the destination, it will be skipped unless -Force is used.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Alert
        The alert(s) to process. This list is auto-populated from the server. If unspecified, all alerts will be processed.

    .PARAMETER ExcludeAlert
        The alert(s) to exclude. This list is auto-populated from the server.

    .PARAMETER IncludeDefaults
        Copy SQL Agent defaults such as FailSafeEmailAddress, ForwardingServer, and PagerSubjectTemplate.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER Force
        If this switch is enabled, the Alert will be dropped and recreated on Destination.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.

    .SYNOPSIS
        Copy-DbaAgentJob migrates jobs from one SQL Server to another.

    .DESCRIPTION
        By default, all jobs are copied. The -Job parameter is auto-populated for command-line completion and can be used to copy only specific jobs.

        If the job already exists on the destination, it will be skipped unless -Force is used.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Job
        The job(s) to process. This list is auto-populated from the server. If unspecified, all jobs will be processed.

    .PARAMETER ExcludeJob
        The job(s) to exclude. This list is auto-populated from the server.

    .PARAMETER DisableOnSource
        If this switch is enabled, the job will be disabled on the source server.

    .PARAMETER DisableOnDestination
        If this switch is enabled, the newly migrated job will be disabled on the destination server.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER Force
        If this switch is enabled, the Job will be dropped and recreated on Destination.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .EXAMPLE
        PS C:\> Copy-DbaAgentJob -Source sqlserver2014a -Destination sqlcluster

        Copies all jobs from sqlserver2014a to sqlcluster, using Windows credentials. If jobs with the same name exist on sqlcluster, they will be skipped.

    .EXAMPLE
        PS C:\> Copy-DbaAgentJob -Source sqlserver2014a -Destination sqlcluster -Job PSJob -SourceSqlCredential $cred -Force

        Copies a single job, the PSJob job from sqlserver2014a to sqlcluster, using SQL credentials for sqlserver2014a and Windows credentials for sqlcluster. If a job with the same name exists on sqlcluster, it will be dropped and recreated because -Force was used.

    .EXAMPLE
        PS C:\> Copy-DbaAgentJob -Source sqlserver2014a -Destination sqlcluster -WhatIf -Force

        Shows what would happen if the command were executed using force.

    .SYNOPSIS
        Copy-DbaAgentJobCategory migrates SQL Agent categories from one SQL Server to another. This is similar to sp_add_category.

        https://msdn.microsoft.com/en-us/library/ms181597.aspx

    .DESCRIPTION
        By default, all SQL Agent categories for Jobs, Operators and Alerts are copied.

        The -OperatorCategories parameter is auto-populated for command-line completion and can be used to copy only specific operator categories.
        The -AgentCategories parameter is auto-populated for command-line completion and can be used to copy only specific agent categories.
        The -JobCategories parameter is auto-populated for command-line completion and can be used to copy only specific job categories.

        If the category already exists on the destination, it will be skipped unless -Force is used.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER CategoryType
        Specifies the Category Type to migrate. Valid options are "Job", "Alert" and "Operator". When CategoryType is specified, all categories from the selected type will be migrated. For granular migrations, use the three parameters below.

    .PARAMETER OperatorCategory
        This parameter is auto-populated for command-line completion and can be used to copy only specific operator categories.

    .PARAMETER AgentCategory
        This parameter is auto-populated for command-line completion and can be used to copy only specific agent categories.

    .PARAMETER JobCategory
        This parameter is auto-populated for command-line completion and can be used to copy only specific job categories.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER Force
        If this switch is enabled, the Category will be dropped and recreated on Destination.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .EXAMPLE
        PS C:\> Copy-DbaAgentJobCategory -Source sqlserver2014a -Destination sqlcluster

        Copies all operator categories from sqlserver2014a to sqlcluster using Windows authentication. If operator categories with the same name exist on sqlcluster, they will be skipped.

    .EXAMPLE
        PS C:\> Copy-DbaAgentJobCategory -Source sqlserver2014a -Destination sqlcluster -OperatorCategory PSOperator -SourceSqlCredential $cred -Force

        Copies a single operator category, the PSOperator operator category from sqlserver2014a to sqlcluster using SQL credentials to authenticate to sqlserver2014a and Windows credentials for sqlcluster. If an operator category with the same name exists on sqlcluster, it will be dropped and recreated because -Force was used.

    .EXAMPLE
        PS C:\> Copy-DbaAgentJobCategory -Source sqlserver2014a -Destination sqlcluster -WhatIf -Force

        Shows what would happen if the command were executed using force.

    .SYNOPSIS
        Copy-DbaAgentOperator migrates operators from one SQL Server to another.

    .DESCRIPTION
        By default, all operators are copied. The -Operators parameter is auto-populated for command-line completion and can be used to copy only specific operators.

        If the associated credentials for the operator do not exist on the destination, it will be skipped. If the operator already exists on the destination, it will be skipped unless -Force is used.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Operator
        The operator(s) to process. This list is auto-populated from the server. If unspecified, all operators will be processed.

    .PARAMETER ExcludeOperator
        The operators(s) to exclude. This list is auto-populated from the server.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER Force
        If this switch is enabled, the Operator will be dropped and recreated on Destination.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .EXAMPLE
        PS C:\> Copy-DbaAgentOperator -Source sqlserver2014a -Destination sqlcluster

        Copies all operators from sqlserver2014a to sqlcluster using Windows credentials. If operators with the same name exist on sqlcluster, they will be skipped.

    .EXAMPLE
        PS C:\> Copy-DbaAgentOperator -Source sqlserver2014a -Destination sqlcluster -Operator PSOperator -SourceSqlCredential $cred -Force

        Copies only the PSOperator operator from sqlserver2014a to sqlcluster using SQL credentials for sqlserver2014a and Windows credentials for sqlcluster. If an operator with the same name exists on sqlcluster, it will be dropped and recreated because -Force was used.

    .EXAMPLE
        PS C:\> Copy-DbaAgentOperator -Source sqlserver2014a -Destination sqlcluster -WhatIf -Force

        Shows what would happen if the command were executed using force.

    <#
    .SYNOPSIS
        Copy-DbaAgentProxy migrates proxy accounts from one SQL Server to another.

    .DESCRIPTION
        By default, all proxy accounts are copied. The -ProxyAccounts parameter is auto-populated for command-line completion and can be used to copy only specific proxy accounts.

        If the associated credential for the account does not exist on the destination, it will be skipped. If the proxy account already exists on the destination, it will be skipped unless -Force is used.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER ProxyAccount
        Only migrate specific proxy accounts

    .PARAMETER ExcludeProxyAccount
        Migrate all proxy accounts except the ones explicitly excluded

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER Force
        If this switch is enabled, the Operator will be dropped and recreated on Destination.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .EXAMPLE
        PS C:\> Copy-DbaAgentProxy -Source sqlserver2014a -Destination sqlcluster

        Copies all proxy accounts from sqlserver2014a to sqlcluster using Windows credentials. If proxy accounts with the same name exist on sqlcluster, they will be skipped.

    .EXAMPLE
        PS C:\> Copy-DbaAgentProxy -Source sqlserver2014a -Destination sqlcluster -ProxyAccount PSProxy -SourceSqlCredential $cred -Force

        Copies only the PSProxy proxy account from sqlserver2014a to sqlcluster using SQL credentials for sqlserver2014a and Windows credentials for sqlcluster. If a proxy account with the same name exists on sqlcluster, it will be dropped and recreated because -Force was used.

    .SYNOPSIS
        Copy SQL Server Agent from one server to another.

    .DESCRIPTION
        A wrapper function that calls the associated Copy command for each of the object types seen in SSMS under SQL Server Agent. This also copies all of the the SQL Agent properties (job history max rows, DBMail profile name, etc.).

        You must have sysadmin access and server version must be SQL Server version 2000 or greater.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER DisableJobsOnDestination
        If this switch is enabled, the jobs will be disabled on Destination after copying.

    .PARAMETER DisableJobsOnSource
        If this switch is enabled, the jobs will be disabled on Source after copying.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .PARAMETER Force
        If this switch is enabled, existing objects on Destination with matching names from Source will be dropped, then copied.

    .SYNOPSIS
        Copies backup devices one by one. Copies both SQL code and the backup file itself.

    .DESCRIPTION
        Backups are migrated using Admin shares. If the destination directory does not exist, SQL Server's default backup directory will be used.

        If a backup device with same name exists on destination, it will not be dropped and recreated unless -Force is used.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER BackupDevice
        BackupDevice to be copied. Auto-populated list of devices. If not provided all BackupDevice(s) will be copied.

    .PARAMETER Force
        If this switch is enabled, backup device(s) will be dropped and recreated if they already exists on destination.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .SYNOPSIS
        Migrates SQL Server Central Management groups and server instances from one SQL Server to another.

    .DESCRIPTION
        Copy-DbaCmsRegServer copies all groups, subgroups, and server instances from one SQL Server to another.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Group
        This is an auto-populated array that contains your Central Management Server top-level groups on Source. You can specify one, many or none.

        If Group is not specified, all groups in your Central Management Server will be copied.

    .PARAMETER SwitchServerName
        If this switch is enabled, all instance names will be changed from Source to Destination.

        Central Management Server does not allow you to add a shared registered server with the same name as the Configuration Server.

    .PARAMETER Force
        If this switch is enabled, group(s) will be dropped and recreated if they already exists on destination.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .EXAMPLE
        PS C:\> Copy-DbaCmsRegServer -Source sqlserver2014a -Destination sqlcluster

        All groups, subgroups, and server instances are copied from sqlserver2014a CMS to sqlcluster CMS.

    .EXAMPLE
        PS C:\> Copy-DbaCmsRegServer -Source sqlserver2014a -Destination sqlcluster -Group Group1,Group3

        Top-level groups Group1 and Group3 along with their subgroups and server instances are copied from sqlserver to sqlcluster.

    .EXAMPLE
        PS C:\> Copy-DbaCmsRegServer -Source sqlserver2014a -Destination sqlcluster -Group Group1,Group3 -SwitchServerName -SourceSqlCredential $SourceSqlCredential -DestinationSqlCredential $DestinationSqlCredential

        Top-level groups Group1 and Group3 along with their subgroups and server instances are copied from sqlserver to sqlcluster. When adding sql instances to sqlcluster, if the server name of the migrating instance is "sqlcluster", it will be switched to "sqlserver".

        If SwitchServerName is not specified, "sqlcluster" will be skipped.

    .SYNOPSIS
        Copy-DbaCredential migrates SQL Server Credentials from one SQL Server to another while maintaining Credential passwords.

    .DESCRIPTION
        By using password decryption techniques provided by Antti Rantasaari (NetSPI, 2014), this script migrates SQL Server Credentials from one server to another while maintaining username and password.

        Credit: https://blog.netspi.com/decrypting-mssql-database-link-server-passwords/

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Credential
        This command requires access to the Windows OS via PowerShell remoting. Use this credential to connect to Windows using alternative credentials.

    .PARAMETER Name
        Only include specific names
        Note: if spaces exist in the credential name, you will have to type "" or '' around it.

    .PARAMETER ExcludeName
        Excluded credential names

    .PARAMETER Identity
        Only include specific identities
        Note: if spaces exist in the credential identity, you will have to type "" or '' around it.

    .PARAMETER ExcludeIdentity
        Excluded identities

    .PARAMETER Force
        If this switch is enabled, the Credential will be dropped and recreated if it already exists on Destination.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .SYNOPSIS
        Migrates SQL Server databases from one SQL Server to another.

    .DESCRIPTION
        This script provides the ability to migrate databases using detach/copy/attach or backup/restore. This script works with named instances, clusters and SQL Server Express Edition.

        By default, databases will be migrated to the destination SQL Server's default data and log directories. You can override this by specifying -ReuseSourceFolderStructure. Filestreams and filegroups are also migrated. Safety is emphasized.

        If you are experiencing issues with Copy-DbaDatabase, please use Backup-DbaDatabase | Restore-DbaDatabase instead.
    
    .PARAMETER Source
        Source SQL Server.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You may specify multiple servers.

        Note that when using -BackupRestore with multiple servers, the backup will only be performed once and backups will be deleted at the end (if you didn't specify -NoBackupCleanup).

        When using -DetachAttach with multiple servers, -Reattach must be specified.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Database
        Migrates only specified databases. This list is auto-populated from the server for tab completion. Multiple databases may be specified as a collection.

    .PARAMETER ExcludeDatabase
        Excludes specified databases when performing -AllDatabases migrations. This list is auto-populated from the Source for tab completion.

    .PARAMETER AllDatabases
        If this switch is enabled, all user databases will be migrated. System and support databases will not be migrated. Requires -BackupRestore or -DetachAttach.

    .PARAMETER BackupRestore
        If this switch is enabled, the copy-only backup and restore method will be used to migrate the database(s). This method requires that you specify -SharedPath in a valid UNC format (\\server\share).

        Backups will be immediately deleted after use unless -NoBackupCleanup is specified.

    .PARAMETER SharedPath
        Specifies the network location for the backup files. The SQL Server service accounts must have read/write permission on this path.

    .PARAMETER WithReplace
        If this switch is enabled, the restore is executed with WITH REPLACE.

    .PARAMETER NoRecovery
        If this switch is enabled, the restore is executed with WITH NORECOVERY. Ideal for staging.

    .PARAMETER NoBackupCleanup
        If this switch is enabled, backups generated by this cmdlet will not be deleted after they are restored. The default behavior is to delete these backups.

    .PARAMETER NumberFiles
        Number of files to split the backup. Default is 3.

    .PARAMETER DetachAttach
        If this switch is enabled, the detach/copy/attach method is used to perform database migrations. No files are deleted on Source. If Destination attachment fails, the Source database will be reattached. File copies are performed over administrative shares (\\server\x$\mssql) using BITS. If a database is being mirrored, the mirror will be broken prior to migration.

    .PARAMETER Reattach
        If this switch is enabled, all databases are reattached to Source after DetachAttach migration.

    .PARAMETER SetSourceReadOnly
        If this switch is enabled, all migrated databases are set to ReadOnly on Source prior to detach/attach & backup/restore.

        If -Reattach is used, databases are set to read-only after reattaching.

    .PARAMETER ReuseSourceFolderStructure
        If this switch is enabled, databases will be migrated to a data and log directory structure on Destination mirroring that used on Source. By default, the default data and log directories for Destination will be used when the databases are migrated.

        The structure on Source  will be kept exactly, so consider this if you're migrating between different versions and use part of Microsoft's default Sql structure (MSSql12.INSTANCE, etc)

        To reuse Destination folder structure, use the  -WithReplace switch.

    .PARAMETER IncludeSupportDbs
        If this switch is enabled, ReportServer, ReportServerTempDb, SSISDB, and distribution databases will be copied if they exist on Source. A log file named $SOURCE-$destinstance-$date-Sqls.csv will be written to the current directory.

        Use of this switch requires -BackupRestore or -DetachAttach as well.

    .PARAMETER InputObject
        Enables piped input from Get-DbaDatabase

    .PARAMETER UseLastBackup
        Use the last full, diff and logs instead of performing backups. Note that the backups must exist in a location accessible by all destination servers, such a network share.

    .PARAMETER Continue
        If specified, will to attempt to restore transaction log backups on top of existing database(s) in Recovering or Standby states. Only usable with -UseLastBackup

    .PARAMETER NoCopyOnly
        If this switch is enabled, backups will be taken without COPY_ONLY. This will break the LSN backup chain, which will interfere with the restore chain of the database.

        By default this switch is disabled, so backups will be taken with COPY_ONLY. This will preserve the LSN backup chain.

        For more details please refer to this MSDN article - https://msdn.microsoft.com/en-us/library/ms191495.aspx

    .PARAMETER NewName
        If a single database is being copied, this will be used to rename the database during the copy process. Any occurrence of the original database name in the physical file names will be replaced with NewName
        If specified with multiple databases a warning will be raised and the copy stopped

        This option is mutually exclusive of Prefix

    .PARAMETER Prefix
        All copied database names and physical files will be prefixed with this string

        This option is mutually exclusive of NewName

    .PARAMETER SetSourceOffline
        If this switch is enabled, the Source database will be set to Offline after being copied.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .PARAMETER Force
        If this switch is enabled, existing databases on Destination with matching names from Source will be dropped.
        If using -DetachReattach, mirrors will be broken and the database(s) dropped from Availability Groups.
        If using -SetSourceReadonly, this will instantly roll back any open transactions that may be stopping the process.

        Limitations:
        - Doesn't cover what it doesn't cover (replication, certificates, etc)
        - SQL Server 2000 databases cannot be directly migrated to SQL Server 2012 and above.

    .EXAMPLE
        PS C:\> Copy-DbaDatabase -Source sql2014a -Destination sql2014b -Database TestDB -BackupRestore -SharedPath \\fileshare\sql\migration

        Migrates a single user database TestDB using Backup and restore from instance sql2014a to sql2014b. Backup files are stored in \\fileshare\sql\migration.

    .EXAMPLE
        PS C:\> Copy-DbaDatabase -Source sql2012 -Destination sql2014, sql2016 -DetachAttach -Reattach

        Databases will be migrated from sql2012 to both sql2014 and sql2016 using the detach/copy files/attach method.The following will be performed: kick all users out of the database, detach all data/log files, move files across the network over an admin share (\\SqlSERVER\M$\MSSql...), attach file on destination server, reattach at source. If the database files (*.mdf, *.ndf, *.ldf) on *destination* exist and aren't in use, they will be overwritten.

    .EXAMPLE
        PS C:\> Copy-DbaDatabase -Source sql2014a -Destination sqlcluster, sql2016 -BackupRestore -UseLastBackup -Force

        Migrates all user databases to sqlcluster and sql2016 using the last Full, Diff and Log backups from sql204a. If the databases exists on the destinations, they will be dropped prior to attach.

        Note that the backups must exist in a location accessible by all destination servers, such a network share.

    .EXAMPLE
        PS C:\> Copy-DbaDatabase -Source sql2014a -Destination sqlcluster -ExcludeDatabase Northwind, pubs -IncludeSupportDbs -Force -BackupRestore -SharedPath \\fileshare\sql\migration

        Migrates all user databases except for Northwind and pubs by using backup/restore (copy-only). Backup files are stored in \\fileshare\sql\migration. If the database exists on the destination, it will be dropped prior to attach.

        It also includes the support databases (ReportServer, ReportServerTempDb, distribution).

    .SYNOPSIS
        Migrates user SQL Data Collector collection sets. SQL Data Collector configuration is on the agenda, but it's hard.

    .DESCRIPTION
        By default, all data collector objects are migrated. If the object already exists on the destination, it will be skipped unless -Force is used.

        The -CollectionSet parameter is auto-populated for command-line completion and can be used to copy only specific objects.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2008 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination Sql Server. You must have sysadmin access and server version must be SQL Server version 2008 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER CollectionSet
        The collection set(s) to process - this list is auto-populated from the server. If unspecified, all collection sets will be processed.

    .PARAMETER ExcludeCollectionSet
        The collection set(s) to exclude - this list is auto-populated from the server

    .PARAMETER NoServerReconfig
        Upcoming parameter to enable server reconfiguration

    .PARAMETER WhatIf
        Shows what would happen if the command were to run. No actions are actually performed.

    .PARAMETER Confirm
        Prompts you for confirmation before executing any changing operations within the command.

    .PARAMETER Force
        If collection sets exists on destination server, it will be dropped and recreated.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .SYNOPSIS
        Copy-DbaDbAssembly migrates assemblies from one SQL Server to another.

    .DESCRIPTION
        By default, all assemblies are copied.

        If the assembly already exists on the destination, it will be skipped unless -Force is used.

        This script does not yet copy dependencies or dependent objects.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Assembly
        The assembly(ies) to process. This list is auto-populated from the server. If unspecified, all assemblies will be processed.

    .PARAMETER ExcludeAssembly
        The assembly(ies) to exclude. This list is auto-populated from the server.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .PARAMETER Force
        If this switch is enabled, existing assemblies on Destination with matching names from Source will be dropped.

    .EXAMPLE
        PS C:\> Copy-DbaDbAssembly -Source sqlserver2014a -Destination sqlcluster

        Copies all assemblies from sqlserver2014a to sqlcluster using Windows credentials. If assemblies with the same name exist on sqlcluster, they will be skipped.

    .EXAMPLE
        PS C:\> Copy-DbaDbAssembly -Source sqlserver2014a -Destination sqlcluster -Assembly dbname.assemblyname, dbname3.anotherassembly -SourceSqlCredential $cred -Force

        Copies two assemblies, the dbname.assemblyname and dbname3.anotherassembly from sqlserver2014a to sqlcluster using SQL credentials for sqlserver2014a and Windows credentials for sqlcluster. If an assembly with the same name exists on sqlcluster, it will be dropped and recreated because -Force was used.

        In this example, anotherassembly will be copied to the dbname3 database on the server sqlcluster.

    .EXAMPLE
        PS C:\> Copy-DbaDbAssembly -Source sqlserver2014a -Destination sqlcluster -WhatIf -Force

        Shows what would happen if the command were executed using force.

    .SYNOPSIS
        Migrates Mail Profiles, Accounts, Mail Servers and Mail Server Configs from one SQL Server to another.

    .DESCRIPTION
        By default, all mail configurations for Profiles, Accounts, Mail Servers and Configs are copied.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Type
        Specifies the object type to migrate. Valid options are "Job", "Alert" and "Operator". When Type is specified, all categories from the selected type will be migrated.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .PARAMETER Force
        If this switch is enabled, existing objects on Destination with matching names from Source will be dropped.

    .SYNOPSIS
        Copies the configuration of a Query Store enabled database and sets the copied configuration on other databases.

    .DESCRIPTION
        Copies the configuration of a Query Store enabled database and sets the copied configuration on other databases.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2016 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER SourceDatabase
        Specifies the database to copy the Query Store configuration from.

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2016 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER DestinationDatabase
        Specifies a list of databases that will receive a copy of the Query Store configuration of the SourceDatabase.

    .PARAMETER Exclude
        Specifies a list of databases which will NOT receive a copy of the Query Store configuration.

    .PARAMETER AllDatabases
        If this switch is enabled, the Query Store configuration will be copied to all databases on the destination instance.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    <#
    .SYNOPSIS
        Copies data between SQL Server tables.

    .DESCRIPTION
        Copies data between SQL Server tables using SQL Bulk Copy.
        The same can be achieved also doing
        $sourcetable = Invoke-DbaQuery -SqlInstance instance1 ... -As DataTable
        Write-DbaDataTable -SqlInstance ... -InputObject $sourcetable
        but it will force buffering the contents on the table in memory (high RAM usage for large tables).
        With this function, a streaming copy will be done in the most speedy and least resource-intensive way.

    .PARAMETER SqlInstance
        Source SQL Server.You must have sysadmin access and server version must be SQL Server version 2000 or greater.

    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination Sql Server. You must have sysadmin access and server version must be SQL Server version 2000 or greater.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Database
        The database to copy the table from.

    .PARAMETER DestinationDatabase
        The database to copy the table to. If not specified, it is assumed to be the same of Database

    .PARAMETER Table
        Define a specific table you would like to use as source. You can specify a three-part name like db.sch.tbl.
        If the object has special characters please wrap them in square brackets [ ].
        This dbo.First.Table will try to find table named 'Table' on schema 'First' and database 'dbo'.
        The correct way to find table named 'First.Table' on schema 'dbo' is passing dbo.[First.Table]

    .PARAMETER DestinationTable
        The table you want to use as destination. If not specified, it is assumed to be the same of Table

    .PARAMETER Query
        If you want to copy only a portion of a table or selected tables, specify the query.
        Ensure to select all required columns. Calculated Columns or columns with default values may be excluded.
        The tablename should be a full three-part name in form [Database].[Schema].[Table]

    .PARAMETER AutoCreateTable
        Creates the destination table if it does not already exist, based off of the "Export..." script of the source table.

    .PARAMETER BatchSize
        The BatchSize for the import defaults to 5000.

    .PARAMETER NotifyAfter
        Sets the option to show the notification after so many rows of import

    .PARAMETER NoTableLock
        If this switch is enabled, a table lock (TABLOCK) will not be placed on the destination table. By default, this operation will lock the destination table while running.

    .PARAMETER CheckConstraints
        If this switch is enabled, the SqlBulkCopy option to process check constraints will be enabled.

        Per Microsoft "Check constraints while data is being inserted. By default, constraints are not checked."

    .PARAMETER FireTriggers
        If this switch is enabled, the SqlBulkCopy option to fire insert triggers will be enabled.

        Per Microsoft "When specified, cause the server to fire the insert triggers for the rows being inserted into the Database."

    .PARAMETER KeepIdentity
        If this switch is enabled, the SqlBulkCopy option to preserve source identity values will be enabled.

        Per Microsoft "Preserve source identity values. When not specified, identity values are assigned by the destination."

    .PARAMETER KeepNulls
        If this switch is enabled, the SqlBulkCopy option to preserve NULL values will be enabled.

        Per Microsoft "Preserve null values in the destination table regardless of the settings for default values. When not specified, null values are replaced by default values where applicable."

    .PARAMETER Truncate
        If this switch is enabled, the destination table will be truncated after prompting for confirmation.

    .PARAMETER BulkCopyTimeOut
        Value in seconds for the BulkCopy operations timeout. The default is 30 seconds.

    .PARAMETER InputObject
        Enables piping of Table objects from Get-DbaDbTable

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .SYNOPSIS
        Copy-DbaEndpoint migrates server endpoints from one SQL Server to another.

    .DESCRIPTION
        By default, all endpoints are copied.

        If the endpoint already exists on the destination, it will be skipped unless -Force is used.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Endpoint
        The endpoint(s) to process. This list is auto-populated from the server. If unspecified, all endpoints will be processed.

    .PARAMETER ExcludeEndpoint
        The endpoint(s) to exclude. This list is auto-populated from the server.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .PARAMETER Force
        If this switch is enabled, existing endpoints on Destination with matching names from Source will be dropped.

    .EXAMPLE
        PS C:\> Copy-DbaEndpoint -Source sqlserver2014a -Destination sqlcluster

        Copies all server endpoints from sqlserver2014a to sqlcluster, using Windows credentials. If endpoints with the same name exist on sqlcluster, they will be skipped.

    .EXAMPLE
        PS C:\> Copy-DbaEndpoint -Source sqlserver2014a -SourceSqlCredential $cred -Destination sqlcluster -Endpoint tg_noDbDrop -Force

        Copies only the tg_noDbDrop endpoint from sqlserver2014a to sqlcluster using SQL credentials for sqlserver2014a and Windows credentials for sqlcluster. If an endpoint with the same name exists on sqlcluster, it will be dropped and recreated because -Force was used.

    .EXAMPLE
        PS C:\> Copy-DbaEndpoint -Source sqlserver2014a -Destination sqlcluster -WhatIf -Force

        Shows what would happen if the command were executed using force.

    .SYNOPSIS
        Copy-DbaLinkedServer migrates Linked Servers from one SQL Server to another. Linked Server logins and passwords are migrated as well.

    .DESCRIPTION
        By using password decryption techniques provided by Antti Rantasaari (NetSPI, 2014), this script migrates SQL Server Linked Servers from one server to another, while maintaining username and password.

    .PARAMETER Source
        Source SQL Server (2005 and above). You must have sysadmin access to both SQL Server and Windows.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server (2005 and above). You must have sysadmin access to both SQL Server and Windows.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER LinkedServer
        The linked server(s) to process - this list is auto-populated from the server. If unspecified, all linked servers will be processed.

    .PARAMETER ExcludeLinkedServer
        The linked server(s) to exclude - this list is auto-populated from the server

    .PARAMETER UpgradeSqlClient
        Upgrade any SqlClient Linked Server to the current Version

    .PARAMETER WhatIf
        Shows what would happen if the command were to run. No actions are actually performed.

    .PARAMETER Confirm
        Prompts you for confirmation before executing any changing operations within the command.

    .PARAMETER Force
        By default, if a Linked Server exists on the source and destination, the Linked Server is not copied over. Specifying -force will drop and recreate the Linked Server on the Destination server.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.

    .SYNOPSIS
        Migrates logins from source to destination SQL Servers. Supports SQL Server versions 2000 and newer.

    .DESCRIPTION
        SQL Server 2000: Migrates logins with SIDs, passwords, server roles and database roles.

        SQL Server 2005 & newer: Migrates logins with SIDs, passwords, defaultdb, server roles & securables, database permissions & securables, login attributes (enforce password policy, expiration, etc.)

        The login hash algorithm changed in SQL Server 2012, and is not backwards compatible with previous SQL Server versions. This means that while SQL Server 2000 logins can be migrated to SQL Server 2012, logins created in SQL Server 2012 can only be migrated to SQL Server 2012 and above.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Login
        The login(s) to process. Options for this list are auto-populated from the server. If unspecified, all logins will be processed.

    .PARAMETER ExcludeLogin
        The login(s) to exclude. Options for this list are auto-populated from the server.

    .PARAMETER ExcludeSystemLogins
        If this switch is enabled, NT SERVICE accounts will be skipped.

    .PARAMETER ExcludePermissionSync
        Skips permission syncs

    .PARAMETER SyncOnly
        If this switch is enabled, only SQL Server login permissions, roles, etc. will be synced. Logins and users will not be added or dropped.  If a matching Login does not exist on the destination, the Login will be skipped.
        Credential removal is not currently supported for this parameter.

    .PARAMETER SyncSaName
        If this switch is enabled, the name of the sa account will be synced between Source and Destination

    .PARAMETER OutFile
        Calls Export-DbaLogin and exports all logins to a T-SQL formatted file. This does not perform a copy, so no destination is required.

    .PARAMETER InputObject
        Takes the parameters required from a Login object that has been piped into the command

    .PARAMETER LoginRenameHashtable
        Pass a hash table into this parameter to be passed into Rename-DbaLogin to update the Login and mappings after the Login is completed.

    .PARAMETER KillActiveConnection
        If this switch and -Force are enabled, all active connections and sessions on Destination will be killed.

        A login cannot be dropped when it has active connections on the instance.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER Force
        If this switch is enabled, the Login(s) will be dropped and recreated on Destination. Logins that own Agent jobs cannot be dropped at this time.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

        https://dbatools.io/Copy-DbaLogin

    .EXAMPLE
        PS C:\> Copy-DbaLogin -Source sqlserver2014a -Destination sqlcluster -Force

        Copies all logins from Source Destination. If a SQL Login on Source exists on the Destination, the Login on Destination will be dropped and recreated.

        If active connections are found for a login, the copy of that Login will fail as it cannot be dropped.

    .EXAMPLE
        PS C:\> Copy-DbaLogin -Source sqlserver2014a -Destination sqlcluster -Force -KillActiveConnection

        Copies all logins from Source Destination. If a SQL Login on Source exists on the Destination, the Login on Destination will be dropped and recreated.

        If any active connections are found they will be killed.

    .EXAMPLE
        PS C:\> Copy-DbaLogin -Source sqlserver2014a -Destination sqlcluster -ExcludeLogin realcajun -SourceSqlCredential $scred -DestinationSqlCredential $dcred

        Copies all Logins from Source to Destination except for realcajun using SQL Authentication to connect to both instances.

        If a Login already exists on the destination, it will not be migrated.

    .EXAMPLE
        PS C:\> Copy-DbaLogin -Source sqlserver2014a -Destination sqlcluster -Login realcajun, netnerds -force

        Copies ONLY Logins netnerds and realcajun. If Login realcajun or netnerds exists on Destination, the existing Login(s) will be dropped and recreated.

    .EXAMPLE
        PS C:\> Copy-DbaLogin -Source sqlserver2014a -Destination sqlcluster -SyncOnly

        Syncs only SQL Server login permissions, roles, etc. Does not add or drop logins or users.

        If a matching Login does not exist on Destination, the Login will be skipped.

    .EXAMPLE
        PS C:\> Copy-DbaLogin -LoginRenameHashtable @{ "PreviousUser" = "newlogin" } -Source $Sql01 -Destination Localhost -SourceSqlCredential $sqlcred

        Copies PreviousUser and then renames it to newlogin.

    .EXAMPLE
        PS C:\> Get-DbaLogin -SqlInstance sql2016 | Out-GridView -Passthru | Copy-DbaLogin -Destination sql2017

        Displays all available logins on sql2016 in a grid view, then copies all selected logins to sql2017.

        By default, all policies and conditions are copied. If an object already exist on the destination, it will be skipped unless -Force is used.

        The -Policy and -Condition parameters are auto-populated for command-line completion and can be used to copy only specific objects.

    .PARAMETER Source
        Source SQL Server.You must have sysadmin access and server version must be SQL Server version 2008 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination Sql Server. You must have sysadmin access and server version must be SQL Server version 2008 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Policy
        The policy(ies) to process - this list is auto-populated from the server. If unspecified, all policies will be processed.

    .PARAMETER ExcludePolicy
        The policy(ies) to exclude - this list is auto-populated from the server

    .PARAMETER Condition
        The condition(s) to process - this list is auto-populated from the server. If unspecified, all conditions will be processed.

    .PARAMETER ExcludeCondition
        The condition(s) to exclude - this list is auto-populated from the server

    .PARAMETER Force
        If policies exists on destination server, it will be dropped and recreated.

    .PARAMETER WhatIf
        Shows what would happen if the command were to run. No actions are actually performed.

    .PARAMETER Confirm
        Prompts you for confirmation before executing any changing operations within the command.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .SYNOPSIS
        Migrates Resource Pools

    .DESCRIPTION
        By default, all non-system resource pools are migrated. If the pool already exists on the destination, it will be skipped unless -Force is used.

        The -ResourcePool parameter is auto-populated for command-line completion and can be used to copy only specific objects.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2008 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2008 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER ResourcePool
        Specifies the resource pool(s) to process. Options for this list are auto-populated from the server. If unspecified, all resource pools will be processed.

    .PARAMETER ExcludeResourcePool
        Specifies the resource pool(s) to exclude. Options for this list are auto-populated from the server

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER Force
        If this switch is enabled, the policies will be dropped and recreated on Destination.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    <#
    .SYNOPSIS
        Copy-DbaServerAudit migrates server audits from one SQL Server to another.

    .DESCRIPTION
        By default, all audits are copied. The -Audit parameter is auto-populated for command-line completion and can be used to copy only specific audits.

        If the audit already exists on the destination, it will be skipped unless -Force is used.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Audit
        The audit(s) to process. Options for this list are auto-populated from the server. If unspecified, all audits will be processed.

    .PARAMETER ExcludeAudit
        The audit(s) to exclude. Options for this list are auto-populated from the server.

    .PARAMETER Path
        Destination file path. If not specified, the file path of the source will be used (or the default data directory).

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER Force
        If this switch is enabled, the audits will be dropped and recreated on Destination.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .EXAMPLE
        PS C:\> Copy-DbaServerAudit -Source sqlserver2014a -Destination sqlcluster

        Copies all server audits from sqlserver2014a to sqlcluster, using Windows credentials. If audits with the same name exist on sqlcluster, they will be skipped.

    .EXAMPLE
        PS C:\> Copy-DbaServerAudit -Source sqlserver2014a -Destination sqlcluster -Audit tg_noDbDrop -SourceSqlCredential $cred -Force

        Copies a single audit, the tg_noDbDrop audit from sqlserver2014a to sqlcluster, using SQL credentials for sqlserver2014a and Windows credentials for sqlcluster. If an audit with the same name exists on sqlcluster, it will be dropped and recreated because -Force was used.

    .EXAMPLE
        PS C:\> Copy-DbaServerAudit -Source sqlserver2014a -Destination sqlcluster -WhatIf -Force

        Shows what would happen if the command were executed using force.

    .EXAMPLE
        PS C:\> Copy-DbaServerAudit -Source sqlserver-0 -Destination sqlserver-1 -Audit audit1 -Path 'C:\audit1'

        Copies audit audit1 from sqlserver-0 to sqlserver-1. The file path on sqlserver-1 will be set to 'C:\audit1'.

    <#
    .SYNOPSIS
        Copy-DbaServerTrigger migrates server triggers from one SQL Server to another.

    .DESCRIPTION
        By default, all triggers are copied. The -ServerTrigger parameter is auto-populated for command-line completion and can be used to copy only specific triggers.

        If the trigger already exists on the destination, it will be skipped unless -Force is used.

    .PARAMETER Source
        Source SQL Server.You must have sysadmin access and server version must be SQL Server version 2000 or greater.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination Sql Server. You must have sysadmin access and server version must be SQL Server version 2000 or greater.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER ServerTrigger
        The Server Trigger(s) to process - this list is auto-populated from the server. If unspecified, all Server Triggers will be processed.

    .PARAMETER ExcludeServerTrigger
        The Server Trigger(s) to exclude - this list is auto-populated from the server

    .PARAMETER WhatIf
        Shows what would happen if the command were to run. No actions are actually performed.

    .PARAMETER Confirm
        Prompts you for confirmation before executing any changing operations within the command.

    .PARAMETER Force
        Drops and recreates the Trigger if it exists

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

        Copies all server triggers from sqlserver2014a to sqlcluster, using Windows credentials. If triggers with the same name exist on sqlcluster, they will be skipped.

    .EXAMPLE
        PS C:\> Copy-DbaServerTrigger -Source sqlserver2014a -Destination sqlcluster -ServerTrigger tg_noDbDrop -SourceSqlCredential $cred -Force

        Copies a single trigger, the tg_noDbDrop trigger from sqlserver2014a to sqlcluster, using SQL credentials for sqlserver2014a and Windows credentials for sqlcluster. If a trigger with the same name exists on sqlcluster, it will be dropped and recreated because -Force was used.

    .SYNOPSIS
        Copy-DbaSsisCatalog migrates Folders, SSIS projects, and environments from one SQL Server to another.

    .DESCRIPTION
        By default, all folders, projects, and environments are copied. The -Project parameter can be specified to copy only one project, if desired.

        The parameters get more granular from the Folder level. For example, specifying -Folder will only deploy projects/environments from within that folder.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2012 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2012 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Force
        If this switch is enabled, the SSIS Catalog will be dropped and recreated on Destination if it already exists.

    .PARAMETER Project
        Specifies a source Project name.

    .PARAMETER Folder
        Specifies a source folder name.

    .PARAMETER Environment
        Specifies an environment to copy.

    .PARAMETER EnableSqlClr
        If this switch is enabled and Destination does not have the SQL CLR configuration option enabled, user prompts for enabling it on Destination will be skipped. SQL CLR is required for SSISDB.

    .PARAMETER CreateCatalogPassword
        Specifies a secure string to use in creating an SSISDB catalog on Destination. If this is specified, prompts for the password will be skipped.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .EXAMPLE
        PS C:\> Copy-DbaSsisCatalog -Source sqlserver2014a -Destination sqlcluster

        Copies all folders, environments and SSIS Projects from sqlserver2014a to sqlcluster, using Windows credentials to authenticate to both instances. If folders with the same name exist on the destination they will be skipped, but projects will be redeployed.

    .EXAMPLE
        PS C:\> Copy-DbaSsisCatalog -Source sqlserver2014a -Destination sqlcluster -Project Archive_Tables -SourceSqlCredential $cred -Force

        Copies a single Project, the Archive_Tables Project, from sqlserver2014a to sqlcluster using SQL credentials to authenticate to sqlserver2014a and Windows credentials to authenticate to sqlcluster. If a Project with the same name exists on sqlcluster, it will be deleted and recreated because -Force was used.

    .EXAMPLE
        PS C:\> Copy-DbaSsisCatalog -Source sqlserver2014a -Destination sqlcluster -WhatIf -Force

        Shows what would happen if the command were executed using force.

    .EXAMPLE
        PS C:\> $SecurePW = Read-Host "Enter password" -AsSecureString
        PS C:\> Copy-DbaSsisCatalog -Source sqlserver2014a -Destination sqlcluster -CreateCatalogPassword $SecurePW

        Deploy entire SSIS catalog to an instance without a destination catalog. User prompts for creating the catalog on Destination will be bypassed.

    .SYNOPSIS
        Imports all user objects found in source SQL Server's master, msdb and model databases to the destination.

    .DESCRIPTION
        Imports all user objects found in source SQL Server's master, msdb and model databases to the destination. This is useful because many DBAs store backup/maintenance procs/tables/triggers/etc (among other things) in master or msdb.

        It is also useful for migrating objects within the model database.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Classic
        Perform the migration the old way

    .PARAMETER Force
        Drop destination objects first. Has no effect if you use Classic. This doesn't work really well, honestly.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .SYNOPSIS
        Migrates SQL Extended Event Sessions except the two default sessions, AlwaysOn_health and system_health.

    .DESCRIPTION
        Migrates SQL Extended Event Sessions except the two default sessions, AlwaysOn_health and system_health.

        By default, all non-system Extended Events are migrated.

    .PARAMETER Source
        Source SQL Server. You must have sysadmin access and server version must be SQL Server version 2000 or higher.

    .PARAMETER SourceSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Destination
        Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher.

    .PARAMETER DestinationSqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER XeSession
        The Extended Event Session(s) to process. This list is auto-populated from the server. If unspecified, all Extended Event Sessions will be processed.

    .PARAMETER ExcludeXeSession
        The Extended Event Session(s) to exclude. This list is auto-populated from the server.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .PARAMETER Force
        If this switch is enabled, existing Extended Events sessions on Destination with matching names from Source will be dropped.

function Disable-DbaAgHadr {
    <#
    .SYNOPSIS
        Disables the Hadr service setting on the specified SQL Server.

    .DESCRIPTION
        In order to build an AG a cluster has to be built and then the Hadr enabled for the SQL Server
        service. This function disables that feature for the SQL Server service.

    .PARAMETER SqlInstance
        The target SQL Server instance or instances.

    .PARAMETER Credential
        Credential object used to connect to the Windows server as a different user

    .PARAMETER WhatIf
        Shows what would happen if the command were to run. No actions are actually performed.

    .PARAMETER Confirm
        Prompts you for confirmation before executing any changing operations within the command.

    .PARAMETER Force
        Will restart SQL Server and SQL Server Agent service to apply the change.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    <#
    .SYNOPSIS
        Detach a SQL Server Database.

    .DESCRIPTION
        This command detaches one or more SQL Server databases. If necessary, -Force can be used to break mirrors and remove databases from availability groups prior to detaching.

    .PARAMETER SqlInstance
        The target SQL Server instance or instances.

    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Database
        The database(s) to detach.

    .PARAMETER FileStructure
        A StringCollection object value that contains a list database files. If FileStructure is not specified, BackupHistory will be used to guess the structure.

    .PARAMETER InputObject
        A collection of databases (such as returned by Get-DbaDatabase), to be detached.

    .PARAMETER UpdateStatistics
        If this switch is enabled, statistics for the database will be updated prior to detaching it.

    .PARAMETER Force
        If this switch is enabled and the database is part of a mirror, the mirror will be broken. If the database is part of an Availability Group, it will be removed from the AG.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .EXAMPLE
        PS C:\> Detach-DbaDatabase -SqlInstance sql2016b -Database SharePoint_Config, WSS_Logging

        Detaches SharePoint_Config and WSS_Logging from sql2016b

    .EXAMPLE
        PS C:\> Get-DbaDatabase -SqlInstance sql2016b -Database 'PerformancePoint Service Application_10032db0fa0041df8f913f558a5dc0d4' | Detach-DbaDatabase -Force

        Detaches 'PerformancePoint Service Application_10032db0fa0041df8f913f558a5dc0d4' from sql2016b. Since Force was specified, if the database is part of mirror, the mirror will be broken prior to detaching.

        If the database is part of an Availability Group, it will first be dropped prior to detachment.

    .EXAMPLE
        PS C:\> Get-DbaDatabase -SqlInstance sql2016b -Database WSS_Logging | Detach-DbaDatabase -Force -WhatIf

        Shows what would happen if the command were to execute (without actually executing the detach/break/remove commands).

function Enable-DbaFilestream {
    <#
    .SYNOPSIS
        Enables FileStream on specified SQL Server instances

    .DESCRIPTION
        Connects to the specified SQL Server instances, and Enables the FileStream feature to the required value

        To perform the action, the SQL Server instance must be restarted. By default we will prompt for confirmation for this action, this can be overridden with the -Force switch

    .PARAMETER SqlInstance
        The target SQL Server instance or instances. Defaults to localhost.

    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Credential
        Login to the target server using alternative credentials.

    .PARAMETER FileStreamLevel
        The level to of FileStream to be enabled:
        1 or TSql - T-Sql Access Only
        2 or TSqlIoStreaming - T-Sql and Win32 access enabled
        3 or TSqlIoStreamingRemoteClient T-Sql, Win32 and Remote access enabled

    .PARAMETER ShareName
        Specifies the Windows file share name to be used for storing the FILESTREAM data.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .PARAMETER Force
        Restart SQL Instance after changes. Use this parameter with care as it overrides whatif.

    .PARAMETER WhatIf
        Shows what would happen if the command runs. The command is not run unless Force is specified.

    .PARAMETER Confirm
        Prompts you for confirmation before running the command.

    .EXAMPLE
        PS C:\> Enable-DbaFilestream -SqlInstance server1\instance2 -FileStreamLevel TSql
        PS C:\> Enable-DbaFilestream -SqlInstance server1\instance2 -FileStreamLevel 1

        These commands are functionally equivalent, both will set Filestream level on server1\instance2 to T-Sql Only

    .EXAMPLE
        PS C:\> Get-DbaFilestream -SqlInstance server1\instance2, server5\instance5, prod\hr | Where-Object InstanceAccessLevel -eq 0 | Enable-DbaFilestream -FileStreamLevel TSqlIoStreamingRemoteClient -Force

        Using this pipeline you can scan a range of SQL instances and enable filestream on only those on which it's disabled.

        Enables Force Encryption for a SQL Server instance.

    .DESCRIPTION
        Enables Force Encryption for a SQL Server instance. Note that this requires access to the Windows Server, not the SQL instance itself.

        This setting is found in Configuration Manager.

    .PARAMETER SqlInstance
        The target SQL Server instance or instances.

    .PARAMETER Credential
        Allows you to login to the computer (not SQL Server instance) using alternative Windows credentials

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.

    <#
    .SYNOPSIS
        This command will help you to automatically grow your transaction log  file in a responsible way (preventing the generation of too many VLFs).

    .DESCRIPTION
        As you may already know, having a transaction log file with too many Virtual Log Files (VLFs) can hurt your database performance in many ways.

        Example:
        Too many VLFs can cause transaction log backups to slow down and can also slow down database recovery and, in extreme cases, even impact insert/update/delete performance.

        References:
        http://www.sqlskills.com/blogs/kimberly/transaction-log-vlfs-too-many-or-too-few/
        http://blogs.msdn.com/b/saponsqlserver/archive/2012/02/22/too-many-virtual-log-files-vlfs-can-cause-slow-database-recovery.aspx
        http://www.brentozar.com/blitz/high-virtual-log-file-vlf-count/

        In order to get rid of this fragmentation we need to grow the file taking the following into consideration:
        - How many VLFs are created when we perform a grow operation or when an auto-grow is invoked?

        Note: In SQL Server 2014 this algorithm has changed (http://www.sqlskills.com/blogs/paul/important-change-vlf-creation-algorithm-sql-server-2014/)

        Attention:
        We are growing in MB instead of GB because of known issue prior to SQL 2012:

        http://connect.microsoft.com/SqlInstance/feedback/details/481594/log-growth-not-working-properly-with-specific-growth-sizes-vlfs-also-not-created-appropriately
        https://connect.microsoft.com/SqlInstance/feedback/details/357502/transaction-log-file-size-will-not-grow-exactly-4gb-when-filegrowth-4gb

        How it works?
        The transaction log will grow in chunks until it reaches the desired size.
        Example: If you have a log file with 8192MB and you say that the target size is 81920MB (80GB) it will grow in chunks of 8192MB until it reaches 81920MB. 8192 -> 16384 -> 24576 ... 73728 -> 81920

    .PARAMETER SqlInstance
        The target SQL Server instance or instances.

    .PARAMETER Database
        The database(s) to process. Options for this list are auto-populated from the server. If unspecified, all databases will be processed.

    .PARAMETER TargetLogSize
        Specifies the target size of the transaction log file in megabytes.

    .PARAMETER IncrementSize
        Specifies the amount the transaction log should grow in megabytes. If this value differs from the suggested value based on your TargetLogSize, you will be prompted to confirm your choice.

        This value will be calculated if not specified.

    .PARAMETER LogFileId
        Specifies the file number(s) of additional transaction log files to grow.

        If this value is not specified, only the first transaction log file will be processed.

    .PARAMETER ShrinkLogFile
        If this switch is enabled, your transaction log files will be shrunk.

    .PARAMETER ShrinkSize
        Specifies the target size of the transaction log file for the shrink operation in megabytes.

    .PARAMETER BackupDirectory
        Specifies the location of your backups. Backups must be performed to shrink the transaction log.

        If this value is not specified, the SQL Server instance's default backup directory will be used.

    .PARAMETER ExcludeDiskSpaceValidation
        If this switch is enabled, the validation for enough disk space using Get-DbaDiskSpace command will be skipped.
        This can be useful when you know that you have enough space to grow your TLog but you don't have PowerShell Remoting enabled to validate it.

    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER ExcludeDatabase
        The database(s) to exclude. Options for this list are auto-populated from the server.

    .PARAMETER WhatIf
        If this switch is enabled, no actions are performed but informational messages will be displayed that explain what would happen if the command were to run.

    .PARAMETER Confirm
        If this switch is enabled, you will be prompted for confirmation before executing any operations that change state.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .EXAMPLE
        PS C:\> Expand-DbaDbLogFile -SqlInstance sqlcluster -Database db1 -TargetLogSize 50000

        Grows the transaction log for database db1 on sqlcluster to 50000 MB and calculates the increment size.

    .EXAMPLE
        PS C:\> Expand-DbaDbLogFile -SqlInstance sqlcluster -Database db1, db2 -TargetLogSize 10000 -IncrementSize 200

        Grows the transaction logs for databases db1 and db2 on sqlcluster to 1000MB and sets the growth increment to 200MB.

    .EXAMPLE
        PS C:\> Expand-DbaDbLogFile -SqlInstance sqlcluster -Database db1 -TargetLogSize 10000 -LogFileId 9

        Grows the transaction log file  with FileId 9 of the db1 database on sqlcluster instance to 10000MB.

    .EXAMPLE
        PS C:\> Expand-DbaDbLogFile -SqlInstance sqlcluster -Database (Get-Content D:\DBs.txt) -TargetLogSize 50000

        Grows the transaction log of the databases specified in the file 'D:\DBs.txt' on sqlcluster instance to 50000MB.

    .EXAMPLE
        PS C:\> Expand-DbaDbLogFile -SqlInstance SqlInstance -Database db1,db2 -TargetLogSize 100 -IncrementSize 10 -ShrinkLogFile -ShrinkSize 10 -BackupDirectory R:\MSSQL\Backup

        Grows the transaction logs for databases db1 and db2 on SQL server SQLInstance to 100MB, sets the incremental growth to 10MB, shrinks the transaction log to 10MB and uses the directory R:\MSSQL\Backup for the required backups.

    .SYNOPSIS
        Exports SQL Server Availability Groups to a T-SQL file.

    .DESCRIPTION
        Exports SQL Server Availability Groups creation scripts to a T-SQL file. This is a function that is not available in SSMS.

    .PARAMETER SqlInstance
        The target SQL Server instance or instances. SQL Server 2012 and above supported.

    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER Path
        The directory name where the output files will be written. A sub directory with the format 'ServerName$InstanceName' will be created. A T-SQL scripts named 'AGName.sql' will be created under this subdirectory for each scripted Availability Group.

    .PARAMETER AvailabilityGroup
        The Availability Group(s) to export - this list is auto-populated from the server. If unspecified, all logins will be processed.

    .PARAMETER ExcludeAvailabilityGroup
        The Availability Group(s) to exclude - this list is auto-populated from the server.

    .PARAMETER NoClobber
        Do not overwrite existing export files.

    .PARAMETER WhatIf
        Shows you what it'd output if you were to run the command

    .PARAMETER Confirm
        Confirms each step/line of output

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .EXAMPLE
        PS C:\> Export-DbaAvailabilityGroup -SqlInstance sql2012

        Exports all Availability Groups from SQL server "sql2012". Output scripts are written to the Documents\SqlAgExports directory by default.

    .EXAMPLE
        PS C:\> Export-DbaAvailabilityGroup -SqlInstance sql2012 -Path C:\temp\availability_group_exports

        Exports all Availability Groups from SQL server "sql2012". Output scripts are written to the C:\temp\availability_group_exports directory.

    .EXAMPLE
        PS C:\> Export-DbaAvailabilityGroup -SqlInstance sql2012 -Path 'C:\dir with spaces\availability_group_exports' -AvailabilityGroup AG1,AG2

        Exports Availability Groups AG1 and AG2 from SQL server "sql2012". Output scripts are written to the C:\dir with spaces\availability_group_exports directory.

    .EXAMPLE
        PS C:\> Export-DbaAvailabilityGroup -SqlInstance sql2014 -Path C:\temp\availability_group_exports -NoClobber

        Exports all Availability Groups from SQL server "sql2014". Output scripts are written to the C:\temp\availability_group_exports directory. If the export file already exists it will not be overwritten.

    .SYNOPSIS
        Exports registered servers and registered server groups to file

    .DESCRIPTION
        Exports registered servers and registered server groups to file

    .PARAMETER SqlInstance
        The target SQL Server instance or instances.

    .PARAMETER SqlCredential
        Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)

    .PARAMETER CredentialPersistenceType
        Used to specify how the login and passwords are persisted. Valid values include None, PersistLoginName and PersistLoginNameAndPassword.

    .PARAMETER Path
        The path to the exported file. If no path is specified, one will be created.

    .PARAMETER InputObject
        Enables piping from Get-DbaCmsRegServer, Get-DbaCmsRegServerGroup, CSVs and other objects.

        If importing from CSV or other object, a column named ServerName is required. Optional columns include Name, Description and Group.

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.

        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.

        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

    .SYNOPSIS
        Exports a dacpac from a server.

    .DESCRIPTION
        Using SQLPackage, export a dacpac from an instance of SQL Server.

        Note - Extract from SQL Server is notoriously flaky - for example if you have three part references to external databases it will not work.

        For help with the extract action parameters and properties, refer to https://msdn.microsoft.com/en-us/library/hh550080(v=vs.103).aspx

    .PARAMETER SqlInstance
        The target SQL Server instance or instances.

    .PARAMETER SqlCredential
        Allows you to login to servers using alternative logins instead Integrated, accepts Credential object created by Get-Credential

    .PARAMETER Path
        The directory where the .dacpac files will be exported to. Defaults to documents.

    .PARAMETER Database
        The database(s) to process - this list is auto-populated from the server. If unspecified, all databases will be processed.

    .PARAMETER ExcludeDatabase
        The database(s) to exclude - this list is auto-populated from the server

    .PARAMETER AllUserDatabases
        Run command against all user databases

    .PARAMETER Type
        Selecting the type of the export: Dacpac (default) or Bacpac.

    .PARAMETER Table
        List of the tables to include into the export. Should be provided as an array of strings: dbo.Table1, Table2, Schema1.Table3.

    .PARAMETER DacOption
        Export options for a corresponding export type. Can be created by New-DbaDacOption -Type Dacpac | Bacpac

    .PARAMETER ExtendedParameters
        Optional parameters used to extract the DACPAC. More information can be found at
        https://msdn.microsoft.com/en-us/library/hh550080.aspx

    .PARAMETER ExtendedProperties
        Optional properties used to extract the DACPAC. More information can be found at
        https://msdn.microsoft.com/en-us/library/hh550080.aspx

    .PARAMETER EnableException
        By default, when something goes wrong we try to catch it, interpret it and give you a friendly warning message.
        This avoids overwhelming you with "sea of red" exceptions, but is inconvenient because it basically disables advanced scripting.
        Using this switch turns this "nice by default" feature off and enables you to catch exceptions with your own try/catch.

        PS C:\> $options.CommandTimeout = 0
        PS C:\> Export-DbaDacPackage -SqlInstance sql2016 -Database DB1 -Options $options

        Uses DacOption object to set the CommandTimeout to 0 then extracts the dacpac for DB1 on sql2016 to $home\Documents\DB1.dacpac including all table data.

    .EXAMPLE
        PS C:\> Export-DbaDacPackage -SqlInstance sql2016 -AllUserDatabases -ExcludeDatabase "DBMaintenance","DBMonitoring" C:\temp

        Exports dacpac packages for all USER databases, excluding "DBMaintenance" & "DBMonitoring", on sql2016 and saves them to C:\temp

    .EXAMPLE
        PS C:\> $moreparams = "/OverwriteFiles:$true /Quiet:$true"
        PS C:\> Export-DbaDacPackage -SqlInstance sql2016 -Database SharePoint_Config -Path C:\temp -ExtendedParameters $moreparams

        Using extended parameters to over-write the files and performs the extraction in quiet mode. Uses command line instead of SMO behind the scenes.
