New Domain & Exchange 2003 Server - Migration from NT4.0 Domain

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 ?

If you are doing Migration, then the Exchange name space should be same as Exchange 5.5.
If you want to use a seperate name space then it would be interorg migration. In this case you would not have to join the Exchange 5.5 Server, you just transfer the users from NT to AD then use Migration Wizard to move the mailboxes.
Best deal is to perform follow the ExDeploy Tools in Exchange 2003, which would tell you what needs to be done.
You can download Deployment Guide from http://www.microsoft.com/downloads/details.aspx?FamilyID=77B6D819-C7B3-42D1-8FBB-FE6339FFA1ED&displaylang=en
Also, you would have to move the users from NT Domain to AD Domain before moving the mailboxes or it would result into Disaster.

Migration is always recommended to be peformed on Test Enviornment first and then on Production.

I did some more reading on this and have concluded that my best bet is to joing the existing Exch 5.5 organization.

Thanks for the info !
