We currently have a single Exchange 2007 Server on Windows Server 2008. It's also a DC and I'd like to split the DC role to a different box.
Is this doable without migrating the mailboxes off to a temporary box, re-installing and migrating back? I.e. can I just demote the server without breaking Exchange completely? I know this was quite painful with Server 2003/Exchange 2003, so I'm trying to get an idea of how much different the process is for Server 2008/Exchange 2007.
