1. configure server B
2. send some test mails to server B while no DNS points at it
3. disable server A (other servers trying to send mail to it start waiting)
4. rsync spool and personal mailboxes from server A to server B
5. make DNS point at server B (hope step 1 was actually right)

for bonus points, do steps 3-5 in under an hour.
Oh, and there are a couple database backed web-apps also running on server A. Those should also be stopped at step 3 and their contents sync-ed over at step 4.
And yes, I pay for the privilege of having my very own custom server out there on the 'net.
