NT 4.0 --> Windows Server 2003

Hi all!! We are planning to migrate (not upgrade) NT 4.0 Domain to Windows Server 2003 domain. I know we have to establish trusts relationship between the 2 domains for migrating data. We will also upgrade Exchange 5.5 to Exchange 2003.

When I install Windows Server 2003, what tools (in sequence) do i need to run to prepare it before joining it with the NT 4.0 Domain?

So far I have the following:

1. DCPROMO
2. ADMT (Active Directory Migration Tool)
3. USMT (User State Migration Tool)

Any comments will be appreciated. Thank you in advance :)
