function Copy-DbaCentralManagementServer { <# .SYNOPSIS Migrates SQL Server Central Management groups and server instances from one SQL Server to another. .DESCRIPTION Copy-DbaCentralManagementServer 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 Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or Trusted). To use: $scred = Get-Credential, then pass $scred object to the -SourceSqlCredential parameter. Windows Authentication will be used if SourceSqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .PARAMETER Destination Destination SQL Server. You must have sysadmin access and the server must be SQL Server 2000 or higher. .PARAMETER DestinationSqlCredential Allows you to login to servers using SQL Logins instead of Windows Authentication (AKA Integrated or Trusted). To use: $dcred = Get-Credential, then pass this $dcred to the -DestinationSqlCredential parameter. Windows Authentication will be used if DestinationSqlCredential is not specified. SQL Server does not accept Windows credentials being passed as credentials. To connect as a different Windows user, run PowerShell as that user. .PARAMETER CMSGroup 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 CMSGroup 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 exist 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. .NOTES Tags: Migration Author: Chrissy LeMaire (@cl), netnerds.net Requires: sysadmin access on SQL Servers Website: https://dbatools.io Copyright: (C) Chrissy LeMaire, clemaire@gmail.com License: GNU GPL v3 https://opensource.org/licenses/GPL-3.0 .LINK https://dbatools.io/Copy-DbaCentralManagementServer .EXAMPLE Copy-DbaCentralManagementServer -Source sqlserver2014a -Destination sqlcluster All groups, subgroups, and server instances are copied from sqlserver's Central Management Server to sqlcluster's Central Management Server. .EXAMPLE Copy-DbaCentralManagementServer -Source sqlserver2014a -Destination sqlcluster -ServerGroup Group1,Group3 Top-level groups Group1 and Group3 along with their subgroups and server instances are copied from sqlserver to sqlcluster. .EXAMPLE Copy-DbaCentralManagementServer -Source sqlserver2014a -Destination sqlcluster -ServerGroup 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. #> [CmdletBinding(DefaultParameterSetName = "Default", SupportsShouldProcess = $true)] Param ( [parameter(Mandatory = $true)] [DbaInstanceParameter]$Source, [PSCredential] $SourceSqlCredential, [parameter(Mandatory = $true)] [DbaInstanceParameter]$Destination, [PSCredential] $DestinationSqlCredential, [object[]]$CMSGroup, [switch]$SwitchServerName, [switch]$Force, [switch][Alias('Silent')]$EnableException ) begin { function Invoke-ParseServerGroup { [cmdletbinding()] param ( $sourceGroup, $destinationGroup, $SwitchServerName ) if ($destinationGroup.Name -eq "DatabaseEngineServerGroup" -and $sourceGroup.Name -ne "DatabaseEngineServerGroup") { $currentServerGroup = $destinationGroup $groupName = $sourceGroup.Name $destinationGroup = $destinationGroup.ServerGroups[$groupName] $copyDestinationGroupStatus = [pscustomobject]@{ SourceServer = $sourceServer.Name DestinationServer = $destServer.Name Name = $groupName Type = "Create Destination Group" Status = $null DateTime = [Sqlcollaborative.Dbatools.Utility.DbaDateTime](Get-Date) } if ($null -ne $destinationGroup) { if ($force -eq $false) { $copyDestinationGroupStatus.Status = "Skipped" $copyDestinationGroupStatus Write-Message -Level Warning -Message "Destination group $groupName exists at destination.
