Replication engine :) Seriously, that's how we do it. Run up a sync_server on the new machine and then sync_client -U each user from the old machine. Obviously, you'll want to suspend delivery and stop IMAP clients for the duration. We do this with some dastardly hacks in the authentication daemon, a database field that our internal tools check before trying to deliver, and a "grep $UserName $confdir/proc/* | xargs kill" moral equivalent. You can probably manage with just removing the imapd and lmtp lines from your cyrus.conf and doing it outside regular hours though.
