Exchange 2000 and 2003 together ?

Posted on 2006-07-11

I just wanted to know if it is possible to run Exchange 2000 and Exchange 2003 servers together in ONE Exchange organization ? I have an AD forest with several child domains. I already have 2 Exchange 2000 servers, and I'll replace one with an Exchange 2003 server.

Does the forest have to prepared through forestprep, or just the domain in which I'll put the new Exchange 2003 server, with / domainprep ?

I plan to install the new Exchange 2003 in that organization, and perform a "move mailbox" operation from the old Exchange 2000 server to the new Exchange 2003 sevrer. Will it work ? Will the users be impacted ?

Thanks a lot !

They are quite happy to co-exist. However you will need to prep the forest and each domain that the Exchange 2003 server is going in to before you can install Exchange 2003.

User impact on move mailbox is minimal. Make sure that they aren't accessing the mailbox while it is being moved, and as long as both the old and the new server are available when they first connect, Outlook will redirect automatically.
