We have an Exchange 2003 Server on Windows Server 2003 Standard. &nbsp;We got a new server with Exchange 2010 on Windows Server 2008 Standard. &nbsp;We ran DC Promo on the new server to make it a Domain Controller and to copy over AD, DNS records, etc. &nbsp;We moved all the mailboxes over to the new Exchange 2010 server. &nbsp;Next step is to remove the old server from the Domain and get rid of it. &nbsp;What should my next steps me? &nbsp;Do I run DC Promo to demote it? &nbsp;Do I have to run any other tools or make any changes? &nbsp;Thanks!
