Upgrade a NT 4.0 domain to Server 2003 with Active Directory

I am installing a 2003 server with Active Directory to a NT 4.0 domain.  Eventually the NT servers will be weeded out a replaced with 2003 servers but for now I am just adding one 2003 server and installing AD. As I see it my options are:

1) Installing 2003 on the new server then Using the Active Directory Migration Tool (ADMT) to copy over user accounts and trusts  OR

2)Installing NT on the new server and making it a PDC and then installing 2003 and AD.

What do you think would be the cleanest safest way to go?  Why is one choice better than the other?  Thanks!

Well #1 isn't an upgrade....instead it is a migration....you are just setting up a new domain and copying over information to it. If you have a large domain with lots of things in it such as file shares, apps, etc. then this can complicate things a bit.

Now, I will say that this is how I did my network...but I only had at the time about 30 comptuers and 60 or so users with nothing else (no files or anything) stored on the server. It was only used for domain authentication....so I did this method and it worked fine.

#2 is the upgrade path

Do you have file shares and such on the server or any other applications that you would need to move over?

One important thing to remember is that in #1 you are creating a new domain....in #2 you are not....so think about how that will affect things. Do your users have local profiles? If they are joined to a new domain, they will get new profiles so you'd have to copy over their old profiles (just something to think about as one thing that happens when you go to a new domain).

Your 2nd option is usually the way to go especially if you have a large domain.

Can you give me more details as to why option #2 is the best way to go?  I need to present the pros and cons of both choices to my client.

Upgrading in general is usually easier than migration since you are dealing with an upgrade instead of a migration to a completely new domain.

They decided for me.  New "LAN" and create new accounts....no migration needed...everything from scratch.
