function Copy-DbaDatabase { <# .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. .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 -NetworkShare in a valid UNC format (\\server\share). Backups will be immediately deleted after use unless -NoBackupCleanup is specified. .PARAMETER NetworkShare 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 A collection of dbobjects from the pipeline. .PARAMETER UseLastBackups 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 -UseLastBackups .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. .NOTES Tags: Migration, Backup, Restore Author: Chrissy LeMaire (@cl), netnerds.net Website: https://dbatools.io Copyright: (c) 2018 by dbatools, licensed under MIT License: MIT https://opensource.org/licenses/MIT Requires: sysadmin access on SQL Servers 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. - Logins within SQL Server 2012 and above logins cannot be migrated to SQL Server 2008 R2 and below. .LINK https://dbatools.io/Copy-DbaDatabase .EXAMPLE PS C:\> Copy-DbaDatabase -Source sql2014a -Destination sql2014b -Database TestDB -BackupRestore -NetworkShare \\fileshare\sql\migration Migrates a single user database TestDB using Backup and restore from instance sql2014a to sql2014b.

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 -UseLastBackups -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 -NetworkShare \\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.
