I know there are several articles out there regarding migration from 2003 AD to 2008 AD but this is a little different and I need validation that what I plan to do will work.

We have 3 sites, each connected via VPN.  For this example, I will call the sites New York, London and Madrid.  New York is the headquarters and London is the 2nd largest site.  Madrid is fairly small.

New York has 3 domain controllers, London has 2 and Madrid has 1.  All are Windows 2003 R2.

We are planning to roll out Windows 7 workstations in all 3 sites, and we plan to use some of the enhanced functionality in Windows 2008 R2 AD.

Would it be sufficient to run adprep /forestprep on the FSMO and adprep /domainprep /gpprep on the infrastructure operations master and then install the Windows 2008 R2 domain controller in New York?

Will there be any problems with the Windows 7 clients in the other sites receiving GP?

One of my colleagues is rather insistent that we must put a 2008 R2 domain controller in each site now, yet I feel that it would be sufficient to prep the domain and keep the 2008 R2 in New York until we can migrate the other domain controllers a few months down the line.
