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 The SQL Server Central Management Server you are migrating from. .PARAMETER SourceSqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/Trusted. To use: $scred = Get-Credential, then pass $scred object to the -SourceSqlCredential 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 Destination The SQL Server Central Management Server you are migrating to. .PARAMETER DestinationSqlCredential Allows you to login to servers using SQL Logins as opposed to Windows Auth/Integrated/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, the Copy-DbaCentralManagementServer script will migrate all groups in your Central Management Server. Note this variable is only populated by top level groups. .PARAMETER SwitchServerName Central Management Server does not allow you to add a shared registered server with the same name as the Configuration Server. If you wish to change all migrating instance names of $Destination to $Source, use this switch. .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 CMS if it exists. .PARAMETER Silent If this switch is enabled, the internal messaging functions will be silenced. .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 In the above example, 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 In the above example, top level Group1 and Group3, along with its 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 In the above example, top level Group1 and Group3, along with its 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]$Silent ) 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 = $destinationGroup 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.
