We are in the process of finishing our move from Exchange 2003 to Exchange 2010.
The network before Exchange 2010 was a Single Windows Server 2003 R2 enterprise machine acting as the Domain Controller and Exchange 2003 server. On this machine Blackberry Enterprise Server was installed as well.
We added a Windows Server 2008 R2 Enterprise box and loaded Exchange 2010 on it. Currently all accept for 2 mailboxes have been moved from the 2003 box to the 2010 box. The last two are our BES users. We are discontinuing Blackberry after this move so we are curious on how to proceed.
Our thought is that we move the last two mailboxes. Uninstall BES, Reboot, Uninstall Exchange 2003, reboot and then are left with a plain old Windows Server 2003 Domain Controller. Any reason why this wouldn't work? or any other steps that must be completed?
