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 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 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 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. .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: MIT https://opensource.org/licenses/MIT .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.
