Nike9090,
Our situation is not similar, as we are on BES 4.1.4.26 and Exchange 2007. I got new SIP credentials from RIM and created a new BES 5.0 SP1 MR1 instance and migrated a small number of users using the Transporter. Then we tested everything to ensure that all is well. We aren't done yet (still about 170 remaining BES 4 users to go). But this is the general way I would recommend to you to proceed. This way, you can move users back if a major problem is discovered.
