Migrate Domain from 2003 32bit to 2008 R2 64 bit?

Need to finally update our 2003 servers (32 bit, some 2003 some 2003 r2) to 64 bit architecture, on Win 2008 R2 servers.

With 32->64 bit I guess I cannot do in-place upgrades, which means installing new servers. I have 4 Domain controllers, but am willing ot move to a virtual environment with the new systems. I assume the domain doesn't care about 32 bt vs 64 bit and that this is simply an OS difference, meaning I don't need to do special prep on the domain relevant to this architectual change, but just for the 2003 -> 2008 one?

As I understand it I should just create a new VM, install Server 2008 R2 on it, update it and get ready to install the role of Domain controller on it. I believe I need to do some work with the domain to support the 2008 DC first? ADPrep or such? I assume after that is done the data would replicate over to the 2008 DC and I could then repeat for another DC, decommissioning the old 2003 servers as I go. I figure I would need ot transfer some roles (FSMO, and the like?) to the new 2008 DCs before I decommision the server that currently holds those roles?

I have an idea I guess of what I need to do, but does anyone have a guide for this sort of thing?

Thanks a lot!

The only difference in the prep is that since your current DCs are 32 bit use adprep32

Take a look at this question I helped with

http://www.experts-exchange.com/OS/Microsoft_Operating_Systems/Server/Windows_Server_2008/Q_26358376.html

Some good guides there in that question

The AD team has a good series on AD and virtualization  http://blogs.technet.com/b/askds/archive/2010/06/10/how-to-virtualize-active-directory-domain-controllers-part-1.aspx

You have the general outline though


Thanks

Mike

involved reading several different articles and piecing the info together. The question wasn't 'answered' here so much as directed to answers. Good starting point though. Thanks!
