Currently we have Exchange 2007 on Windows 2003. We have had some weird errors and microsoft will not support it because it is not on windows 2008 (we are running it on VMWARE).
So we decided to add a new Windows 2008 VM with Exchange 2007 and move all the mailboxes to the new server and shut the old (current) one off.
I have the new machine up and running, Exchange 2007 is installed and of course its sees all the mailboxes on the current Exchange.
Whats the steps to best move the mailboxes, distrubution list etc and what steps to remove the current Exchange once everythign is moved?
