Reindls close, but he omitted the fact that if changing IP, you better shorten the TTL to about 5 mins - 24 hours before you do anything, assuming your default DNS TTL if 24 hrs as most are, if you use longer, than you need to wait that time.
then after a few hours after the change if everythings good, reset your TTL back to 86400 or 1D

Quick question.
We are using both IMAP and POP#.
Question : how can you avoid retrieving an e-mail that has been already retrieved?
by just rsync the complete data from the old to the new server
- first rsync hot while servicers running
- stop services
- second rsync only transfer the differences
- DNS and/or IP change
- start servcies on the new server
the client don't know anything about that
