function Move-DbaRegisteredServerGroup {
    <#
        .SYNOPSIS
             Moves registered server groups around SQL Server Central Management Server (CMS).
 
        .DESCRIPTION
            Moves registered server groups around SQL Server Central Management Server (CMS).
 
        .PARAMETER SqlInstance
            SQL Server name or SMO object representing the SQL Server to connect to.
 
        .PARAMETER SqlCredential
            Login to the target instance using alternative credentials. Windows and SQL Authentication supported. Accepts credential objects (Get-Credential)
 
        .PARAMETER Group
            Specifies one or more groups to include from SQL Server Central Management Server.
 
        .PARAMETER InputObject
            Allows results from Get-DbaRegisteredServerGroup to be piped in
 
        .PARAMETER Id
            Get group by Id(s)
 
        .PARAMETER WhatIf
            Shows what would happen if the command were to run. No actions are actually performed.
 
        .PARAMETER NewGroup
            The new location.
 
        .PARAMETER Confirm
            Prompts you for confirmation before executing any changing operations within the command.
 
        .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.
