So I am in the middle of migrating Exchange 2003 to Exchange 2010. Something happened and my OWA and ECP and Exchange Console and Powershell are hosed. I cannot get into any of them. Is it possible to install another Exchange 2010 server from scratch and move everything to that server. I have a couple mailboxes on 2003 still and was going to try and move the rest of the 203 mailboxes over from the 2003 exchange server. Is this something I can do?
