Been there, done that...
Move your users to Exchange 2007 first
Wait for AD replication (4-6 hours in my world wide environment)
Then use the transporter to move your users.
This was also the recommended method by RIM. So I wanted to find out
why. First I moved my account, using the transporter utility. My
Blackberry worked fine, so I immediately moved my Exchange 2003 mailbox
to Exchange 2007. Blackberry quit working. The only way I could fix it,
remove and re-add my account to the new BES 5.0 server. Oh I also tried
re-adding back to the 4.1 server, and that works as well. There was no
time to discover what was breaking the client when moving the BES
account first. Maybe someone else could shed light on that.

I just got authorization to upgrade out BPS to BES. We will soon
upgrade our Exchange from 2003 to 2007.
In terms of timing, Should I do the BPS->BES upgrade...
1. Before the exchange upgrade,
2. concurrent with the exchange upgrade, or
3. after the exchange upgrade?
In the event that it matters, we are switching from a physical Exchange
server to a fresh install of 2007 on a virtual server with a mailbox
migration. BPS is already on its own virtual 2003 server, and I can
adjust the resources available to the server if necessary.
Thanks.
