I would guess that you could simply copy the user's maildir over to the
new server.

Another tool that I've found useful for such migrations is imapsync
which copies messages and folders from one server to the new server.
One feature I've asked for is to delete messages on the target machine
which do not exist on the source machine.  During our last migration we
ran syncs for about 20 days before we were confident in making the
switchover.  So we deleted all the unread messages on the target server
before our final sync of the accounts.  This seemed to work pretty
well.  We were migrating from Courier IMAP to Cyrus IMAP at a service
provider (Tuffmail.com).
