Adding 2008 server to 2003 domain forest and promoting 2008 to master domain controller.

Hello and thank you for your time and input. Your expertise is always much appreciated and valued.

We have 2003 Enterprise ed. SP2 server. Currently its the main domain controller.
We just purchased a new 2008 std server.
I need to know how to add the 2008 to existing 2003 domain, and later promote demote 2003 as master and promote 2008 to main dc.
To add to the complexity of things. All users have roaming profiles. So their profiles need to be migrated as well.

I know i need to run DC promo on the 2008 box to add to domain.
Do i need to run DC Prep on the 2003 box?
What about the profiles?

What is the process for this.

I know this is a lot...
Many thanks in advance...

Hello thank you for prompt response.

The new server is 2008 R2.

Thank you..
Hi first your senerio does not need any migration tool like admt or so on.
1.First run adprep /domainprep then adprep /forestprep on 2003 machine  this will increase the schema version and make 2008 compatible with 2003 domain
2. Run dcpromo on 2008 r2 machine and dont raise the forest functional level 2008 let it be 2003
3.Then let all the repllication happen gradually with 2003 and 2008 r2 server
4 Now using Ntdsutil transfer all the roles to 2008 server
5.If there is a roaming profile on 2003 server you have to change the path through the registry and GPO .
6.Now you can decommision the 2003 server without any major concern.
Please let me know if there is any confussion.
