Exchange 2012 on SBS 2003 Domain
Posted on 2014-09-16
My customer is running an SBS 2003 domain with Exchange Server 2003 on the server as well. Their applications are not ready for the 64-bit world and have been so highly customized with no documentation such that I don't want to break that which is not broken by moving them to a new server. We do need to move them to Exchange 2012 so I am wondering if I can install Server 2012 (not R2) with Exchange 2012 , move all mailboxes from their current Exchange 2003 to the new Exchange server, decommission the old Exchange, and have Exchange 2012 running on the domain.
