Migration from 2008 SP2 to 2008R2 DC's
I have a Server 2008 SP2 and 32 bit DC. I need to migrate to a Server 2008R2 64bit DC.
What is the easiest way to do this without having to manually recreate users, policies ou’s etc.?

A simple process:
Add the new 64bit machine to the domain
Insert the 2008R2 DVD into the existing DC, if it autoruns cancel it.
Run ADPREP32 /forestprep
and ADPREP32 /domainprep
to update the schema
Promote the new R2 machibe to be a DC (DCPROMO)
you can then transfer the FSMO roles if you want and/or add DNS to the new DC

I have done both adprep for forest and domain but still when I run dcpromo it ask me run run them but like I said I ran both successfully. Does the fact that the new server is a 64 bit vs the old one that is 32 bit have anything to do with the problem?

Thank You.
Verify existing health. Have backups. Adprep. Install new OS. Dcpromo to a DC. Verify replication. Transfer any desired roles. Make a GC if desired. Demote old CCs of desired.
