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.?

Technet has articles on adding DCs. Nothing overly complicated.

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.

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?

No. But make sure you are running the AD prep (it is called adprep32.exe for 32-bit servers) from 2008 R2 media. 2008 (non-r2) is *not* good enough.

Control application downtime with dependency maps

Visualize the interdependencies between application components better with Applications Manager's automated application discovery and dependency mapping feature. Resolve performance issues faster by quickly isolating problematic components.

are you missing adprep32 /domainprep /gpprep

You need to update group policy objects also

Just only to add.

If you wish you may follow an article on my blog which shows all required steps
http://kpytko.pl/2011/08/25/adding-first-windows-server-2008-r2-domain-controller-within-windows-2003-network/

This is for 2008R2 DC within 2003 network but this is exactly the same proces for 2008 environment

Krzysztof
