Confused over 5.5 to E2K3 migration
Hello Gurus
I am very confused with reference to a planned NT to 2003 migration.
We currently have an existing NT4 domain running E5.5
We have purchased new hardware and created a new 2003 domain with E2K3.The 2K3 domain is mixed, there is a trust set up between the NT domain and the 2K3 domain.
We will be migrating the users, department at a time over the next few months. My question(s) are:
How do I join the E2k3 server to the 5.5 org? Do I need to install AD on the NT domain (ie, upgrade the pdc to 2K3)
We need co-existence between the 2 exchange servers, mail will still be coming in to the same gateway, and we need users on the NT domain to receive their mail aswell as new users on the 2K3 domain, how do I achieve this?
I can't use the ADMT because I am not native, I can't go native because the trust needs to be in place to allow access to resources on the NT domain
Please, please help!!
Many thanks in advance

I have read some more white papers since my last post and have installed the ADC and created the connection agreements. I have joined the 2003 server to the 5.5 site, so hopefully should be able to set up a test user on the 2003 domain and be able to receive mail to the E2K3 server. Once I begin migrating I should be able to use the move mailbox method to move my 5.5 mailboxes to E2K3, does that sound correct?

I'm gonna close this one now! Thanks Vahik for your help. I have resolved most of my problems, and now have the co-existence I need between 5.5/2003 Still having a few probs with public folders, but sure to fix them! There is a very good book by WillWillis/Ian Mclean called Implementing and Managing Microsoft Exchange Server 2003 which has helped to.

This is only a small network with 100 users, I don't mind creating the users/groups manually etc, but my biggest problem is that our external mx record points to one gateway, and I need those users on the 5.5 box to receive mail and the new users on the E2K3 box to receive their mail, is this possible?
