Upgrade to 5.0 in mixed Exchange 2003/2007 environment

I have inherited an Exchange 2007/2003 environment.  The HUB/CAS servers are Exchange 2007 while the mailbox server is Exchange 2003.


We are currently on 4.1 and I am in the process of building a BES 5.0 server and plan to migrate.  I'm debating if I need to follow the directions for upgrading for Exchange 2003 or 2007.


My educated guess would be 2003 as BES will most likely still be making all of it's MAPI calls to the mailbox server.  I'm assuming this won't change until I move to Exchange 2010 next year.


Any thoughts/input?

CDO 1.2.1 supports both exchange 2007 and 2003. So you should not have an issue.
