I am trying to move our mail server from a machine with a 2GIG hard drive to a machine with 40Gig's. I have read so many article on microsoft's knowledge base, but I can't find a way to just move the mailboxes to the new machine. I can't partition the new disk the same way as the old disk because there I need to set it up with an extra drive. How do I move the mailboxes and what data do I need to move to the new server from the old server? I looked at where data is stored through the optimizer, but which data must be moved to have our mail server run and to stop users from being disrupted and to avoid users from loosing any data?
