Introducing the first Server 2008 R2 in AD 2003 Environment

I just finished adding the first Server 2008 R2 in our network which is running on AD 2003. I used ADPREP for this. Currently our AD is running on Windows 2003 Server level (Forest/Domain) . I would like to know how to promote the new DC's (I will add two more 2008 R2 DC's in next few weeks) to replace the current DC's running on Server 2003  (Three Domain controllers).

Basically the question is to how to transfer existing roles
 Schema Master
Domain Naming Master
RID Pool Manager
Infrastructure Master

Thanks

Not really. If there is a problem, you'll know when you attempt to demote the old DC's. As for renaming the DC's, after the old machines are demoted, unjoined, and their AD Computer Account has been deleted, you can rename it as you would any other server. However, you may want to keep its old name in the forward lookup zone as a static entry, just incase you missed something along the way.

Thanks,

Thanks. Any precautions during the transfer of roles ? Also Can I rename the new 2008 Server's to the names of the old 2003 Server's after the role transfer is complete?

Three old 2003 servers in production and I have one new 2008 R2 right now followed by two more 2008 R2 Servers.
