New Domain & Exchange 2003 Server - Migration from NT4.0 Domain
Posted on 2006-06-08
I am in the process of migrating from an NT4.0 Domain with Exch 5.5 to an AD 2003 Domain with Exch 2003.
I have created the 2 way trust and am working on getting DNS functioning both ways.
I want to maintain access to resources on both sides of the trust during the migration process.
Here is my question : (forgive my limited knowledge please)
When I first fire up my Exchange 2003 Server, does it matter what I set the "Exchange Namespace" to ?
Can I have a different Exchange environment on the AD Domain side and still make an ADC connection back across to the Exch 5.5 environment for the migration ?
Will this initial choice have a major impact when it comes to migrating the users and mailboxes from the NT4.0 side ?
Ideally I would like to have Exchange 2003 fully functional right away and be able to do some testing on the AD domain before extablishing the connection back across the trust to the NT4.0 Domain.
Can someone please give me some specific info here on what I can and can't do here ?
