Just quickly thinking here; Setup the Exchange before moving anyone over and add the Exchange account to the user's outlook so they have 2 accounts in there. You can then set Exchange to store all incoming mails to the Exchange account even if they come in from QMT. Then once you have everyone in the Exchange, flip the MX so one day they get mail from QMT and the next they get it from Exchange. Then go through and move the mail from one acct. to the other within Outlook and delete the QMT account from outlook. Of course this only works if you have few enough machines to do this sort of sneaker net game.
