How do I migrate 2003 Server (x86) Domain Controller to 2008 R2 (x64)?
Posted on 2010-09-20
I hope you guys can help me out. Back story: I'm kind of forced to upgrade our new server as our lease has expired on our 2k3 DC and we can't buy it out. I also have tight time constraints as the new server has to be out of here by Oct 25th. I've never created a DC before.
I have installed 2008 R2 on the new server, patched it up, and given it an IP.
I'm not really sure what to do next, and I can't really find a detailed guide on how to do 2003 (x86) to 2008 R2 (x64) migration. Do I run DCPROMO to add another DC to the network? or do I do the upgrade the old Windows Server 2003 forest schema to 2008 schema?
Also, how do I upgrade the 2003 AD to the 2008 schema when the disc I have is for x64?
Also, does having a 64 bit DC play nice with our other servers that are running 32 bit (exchange, iis running sharepoint, etc)??
Is this asking for too much trouble? I'm already thinking of reinstalling to 2008 x86.
