One important thing I need to ask is if you are going to a new Exchange Org. If you are then you need to re-install your BES with a new DB and reactivate the devices. BES cannot work between Exchange Orgs, the DB does not support it, neither does Microsoft as far as I know.
If not, then you should be able to perform a knife edge cutover to the machine in the new domain.
Essentially you need 2 way trust between domains and BESAdmin needs correct permissions on the other Exchange Server.
That's it pretty much, it's not a hard switch, it's all in the permissions.
Feel free to ask any questions.
