I've brought this topic up previously, but I thought I'd run it across you
folks one more time to make sure I'm on the right track.  We're preparing to
upgrade a single NT4 domain to a 2003 AD domain, and I'll tentatively be
using the following plan. 

The current PDC (Serv01) is running NT4.  Due to poor management by previous
IT staff, it is also running Proxy Server 2, SQL Server 7, Exchange 5.5, and
one critical third-party application.  It also hosts multiple file shares.
The domain consists of approximately 100 users and 80 workstations, so it is
quite small.

The current BDC (Serv02) is a clean box running NT4 TSE.  I just built it a
few weeks ago for this project.  I intend to use this as a "cold spare" in
case this project goes south.  It is currently a BDC running backup on DNS
and WINS and not much else.

I have two new boxes, Serv03 and Serv04, that haven't been touched as of
yet.


1) Remove Serv02 from network, store as cold spare.
2) Build Serv03 as NT4 box.  Apply patches/SP's.
3) Promote Serv03 to PDC.  Allow time for synchronization.

Should Serv03 be running any specific services (DNS, WINS, etc.) at this
point, before I upgrade it to Windows 2003?


4) Upgrade Serv03 to Server 2003.  Give time to synchronize.

Will I need to move any FSMO roles over, or will this be done automatically?
Serv02 should be the only FSMO role-holder at the end   of the migration,
correct?


5) Install Server 2003 (clean) on Serv04.  Promote to DC.

At this point, the domain would sit in mixed mode for no less than two to
three months while I beg management for money to buy new equipment and
licenses to migrate things away from Serv01.  Do you guys foresee any
complications with this?


6) When apps have been migrated, trash Serv01 softly.


Do you guys foresee any complications with my migration strategy?  The most
important IT asset of this organization is e-mail, so keeping the existing
PDC (Serv01) safe is of paramount importance.  Thanks!
