My company is upgrading from Exchange 2000 to 2007, and I'm in charge of the BES. I just wanted to make sure I have all our ducks in a row, as we only have one SRP, so we can't create a test server:

1) Move BES (version 4.0.4) from old server to new server using the knife-over technique from RIM's documentation.
2) Upgrade BES (on new server) to 4.1.4. Exchange 2000 will still be in place.
3) A few weeks later, the upgrade to Exchange 2007 will begin, at which point, both the 2000 and 2007 servers will exist in parallel for a few weeks while mailboxes are moved. The only thing I plan on doing is installing the MAP CDO client for Exchange 2007 compatibility.

Do these steps look good, or am I missing something? Thanks.
