        .SYNOPSIS
            Moves registered servers around SQL Server Central Management Server (CMS)
 
        .DESCRIPTION
            Moves registered servers 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 Name
            Specifies one or more reg servers to move. Name is the visible name in SSMS CMS interface (labeled Registered Server Name)
 
        .PARAMETER ServerName
            Specifies one or more reg servers to move. Server Name is the actual instance name (labeled Server Name)
 
        .PARAMETER NewGroup
            The new group. If no new group is specified, the default root will used
 
        .PARAMETER InputObject
            Allows results from Get-DbaRegisteredServer to be piped in
 
        .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 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.
