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 Express. 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.You must have sysadmin access and server version must be SQL Server version 2000 or greater. .PARAMETER SourceSqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use: $scred = Get-Credential, this pass $scred object to the param. Windows Authentication will be used if DestinationSqlCredential is not specified. To connect as a different Windows user, run PowerShell as that user. .PARAMETER Destination Destination Sql Server. You must have sysadmin access and server version must be SQL Server version 2000 or greater. .PARAMETER DestinationSqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use: $dcred = Get-Credential, this pass this $dcred to the param. Windows Authentication will be used if DestinationSqlCredential is not specified. To connect as a different Windows user, run PowerShell as that user. .PARAMETER Database Migrates ONLY specified databases. This list is auto-populated for tab completion. Multiple databases are allowed. .PARAMETER ExcludeDatabase Excludes specified databases when performing -AllDatabases migrations. This list is auto-populated for tab completion. .PARAMETER AllDatabases This is a parameter that was included for safety, so you don't accidentally detach/attach all databases without specifying. Migrates user databases. Does not migrate system or support databases. Requires -BackupRestore or -DetachAttach. .PARAMETER BackupRestore Use the a Copy-Only Backup and Restore Method. This parameter requires that you specify -NetworkShare in a valid UNC format (\\server\share) Backups will be immediately deleted after use unless -NoBackupCleanup is specified. .PARAMETER NetworkShare Specifies the network location for the backup files. The Sql Service service accounts must read/write permission to access this location. .PARAMETER WithReplace It's exactly WITH REPLACE. This is useful if you want to stage some complex file paths. .PARAMETER NoRecovery Sets restore to NoRecovery. Ideal for staging. .PARAMETER NoBackupCleanup By default, backups generated by the module will be deleted immediately after they are restored. Use this to skip. .PARAMETER NumberFiles Number of files to split the backup. Default is 3. .PARAMETER DetachAttach Uses the detach/copy/attach method to perform database migrations. No files are deleted on the source. If the destination attachment fails, the source database will be reattached. File copies are performed over administrative shares (\\server\x$\mssql) using BITS. If a database is being mirrored, the mirror will be broken prior to migration. .PARAMETER Reattach Reattaches all source databases after DetachAttach migration. .PARAMETER SetSourceReadOnly Sets all migrated databases to ReadOnly prior to detach/attach & backup/restore. If -Reattach is used, db is set to read-only after reattach. .PARAMETER ReuseSourceFolderStructure By default, databases will be migrated to the destination Sql Server's default data and log directories. You can override this by specifying -ReuseSourceFolderStructure. The same structure on the 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) * note, to reuse destination folder structure, specify -WithReplace .PARAMETER IncludeSupportDbs Migration of ReportServer, ReportServerTempDb, SSIDb, and distribution databases if they exist. A logfile named $SOURCE-$DESTINATION-$date-Sqls.csv will be written to the current directory. Requires -BackupRestore or -DetachAttach. .PARAMETER DatabaseCollection Takes dbobject from pipeline .PARAMETER NoCopyOnly By default, Copy-DbaDatabase backups are backed up with COPY_ONLY, which avoids breaking the LSN backup chain. This parameter will set CopyOnly to $false. .PARAMETER SetSourceOffline Sets the Source db to offline after copy .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 existing databases with matching names. If using -DetachAttach, -Force will break mirrors and drop dbs from Availability Groups. .PARAMETER Silent Use this switch to disable any kind of verbose messages .NOTES Tags: Migration, DisasterRecovery, Backup, Restore Original Author: Chrissy LeMaire (@cl), netnerds.net 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.

Backup files are stored in \\fileshare\sql\migration. .EXAMPLE Copy-DbaDatabase -Source sqlserver2014a -Destination sqlcluster -DetachAttach -Reattach Databases will be migrated from sqlserver2014a to sqlcluster using the detach/copy files/attach method.The following will be perfomed: 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 Copy-DbaDatabase -Source sqlserver2014a -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. It also includes the support databases (ReportServer, ReportServerTempDb, distribution). #> [CmdletBinding(DefaultParameterSetName = "DbBackup", SupportsShouldProcess = $true)] Param ( [parameter(Mandatory = $false)] [DbaInstanceParameter] $Source, [PSCredential] $SourceSqlCredential, [parameter(Mandatory = $true)] [DbaInstanceParameter] $Destination, [PSCredential] $DestinationSqlCredential, [Alias("Databases")] [object[]] $Database, [object[]] $ExcludeDatabase, [Alias("All")] [parameter(ParameterSetName = "DbBackup")] [parameter(ParameterSetName = "DbAttachDetach")] [switch] $AllDatabases, [parameter(Mandatory = $true, ParameterSetName = "DbBackup")] [switch] $BackupRestore, [parameter(Mandatory = $true, ParameterSetName = "DbBackup", HelpMessage = "Specify a valid network share in the format \\server\share that can be accessed by your account and both Sql Server service accounts.")] [string] $NetworkShare, [parameter(ParameterSetName = "DbBackup")] [switch] $WithReplace, [parameter(ParameterSetName = "DbBackup")] [switch] $NoRecovery, [parameter(ParameterSetName = "DbBackup")] [switch] $NoBackupCleanup, [parameter(ParameterSetName = "DbBackup")] [ValidateRange(1, 64)] [int] $NumberFiles = 3, [parameter(Mandatory = $true, ParameterSetName = "DbAttachDetach")] [switch] $DetachAttach, [parameter(ParameterSetName = "DbAttachDetach")] [switch] $Reattach, [parameter(ParameterSetName = "DbBackup")] [parameter(ParameterSetName = "DbAttachDetach")] [switch] $SetSourceReadOnly, [Alias("ReuseFolderstructure")] [parameter(ParameterSetName = "DbBackup")] [parameter(ParameterSetName = "DbAttachDetach")] [switch] $ReuseSourceFolderStructure, [parameter(ParameterSetName = "DbBackup")] [parameter(ParameterSetName = "DbAttachDetach")] [switch] $IncludeSupportDbs, [parameter(ValueFromPipeline = $True)] [object] $DatabaseCollection, [switch] $NoCopyOnly, [switch] $SetSourceOffline, [switch] $Force, [switch] $Silent ) begin { Test-DbaDeprecation -DeprecatedOn "1.0.0" -Silent:$false -Alias Copy-SqlDatabase $CopyOnly = -not $NoCopyOnly function Join-AdminUnc { <# .SYNOPSIS Internal function.
