Readiness failure - 2010 Cannot Coexist with Exch below 2007 SP2 ?

[TekkieDave]

I'm trying to install 2010, and the readiness check is kicking back the following error:

"Coexistence between Exchange Server 2010 and Exchange Server versions older than Exchange Server 2007 SP2 in the same Active Directory Site is not supported."

I currently have (2) 2003 boxes, and one (1) 2007 on a VM. 2010 is going on a brand new machine. THe plan is to move all of the mailboxes onto 2010, and decommission the older equipment.

According to Microsoft, 2010 supports co-existence with mixed 2003 and 2007 environments.

What gives?

I figured out the solution, in case anyone else is looking.

I simply upgraded my exchange 2007 server to SP2, and now the readiness check is showing all green check marks

Thanks anyway guys.
