Yes. But not the way you think - assign old server ip to the new machine with frontend. > Of course, the old IMAP server has to run there too. Wrong. Assign new ip to the old server. Frankly there are simplier ways to do the migration than playing with frontend and mupdate -> perdition. You will use same scheme though - assign the ip users are used to use to the perdition and give new ip to the old server.
