Adding a New Windows 2K3 64bit DC and trasfering roles

Please could someone give me the thumbs up or down!

I have a 2k3 domain with 3 DC's
SVR1 (Orignally the first)
SVR2 (another DC box) and
SVR3 (VM inside another box)

I want to replace SVR1 (holds all the FSMO roles etc and DNS) DHCP done
seperatly

So i DCPROMO new Box called SVR4 and transfer roles in AD U&C "operations"
and install DNS and export and import the data.

Also change the scripts for GPO to point to the SVR4 now as SVR1 will be
decomissioned.

Is this ok? Anything else i need to do?

Many Thanks!!
