Hi. I have upgraded my organization to Exchange 2007 from 2000. Now I want to remove the last 2000 server. I have followed the articel: "How to remove the last Legacy exchange server from an organisation". It says Do not delete any Exchange 2000 administrative groups. How do I do that when I want to uninstall and remove the Exchange 2000 server? The new 2007 server has the Exchange administrative group. Can the 2007 server hold the first administrative group aswell?
