Migration of NT4 to Server 2003

We're a small company of about 55 users moving from NT4\Exchange 5.5 to
W2K3\Exchange2003. The servers are basically;



NT4 BDC (SQL 7 Server)

NT4 PDC (Backup\AntiVirus server)

W2K Standalone (Exchange 5.5)

W2K3 Standalone (file server)



I have a new box to install W2K3 AD and Exchange 2003 on.

The current NT4 domain is an upgrade from 3.51 domain, and the company has a
new name are couple reasons for desiring fresh install and a new domain.



The current thought is to

Install NT4 on an old box, (P2-266) and promote to PDC. Take
offline, use as fallback.

Install W2K3 on new box and create new domain.

Create a trust relationship with the existing NT domain, and use ADMT to
migrate users, groups, computers. (including the existing NT4 BDC's)

Let those changes settle in for a couple weeks.

Install Exchange 2003 on the new AD server

Move the 5.5 accounts to the Exchange 2003

Rebuild the W2K system that held the 5.5 as a W2K3 AD Server



When budget allows, I'll move Exchange 2003 to a W2K3 standalone.



If things started getting flaky with the initial portion, the fallback would
be to take the new W2K3 server offline, put the offline PDC back up, and
possibly promote one of the existing BDCs.



Are there any flaws in that scenario?



My assumption is that with both domains in place, I will gradually move any
service accounts running under the old domain to the corresponding user on
the new domain. I will also have to change the folder permissions on the
file servers from the old domain to the new domain groups. This type of
activity will continue to occur over time and after I think all references
to the old domain have been removed, I can take down the BDCs.



Is this an accurate assessment?



Thanks for your thoughts on this.
