I currently have a 32bit 2003 DC. I have just installed 64 bit 2008 R2 on new server with the view to this replacing 2003 DC.
I didn't want to upgrade current 2003 DC as the box is unstable and old. The idea is to populate the new 2008 DC with the AD schema from 2003 DC then turn it off for good.
All user accounts, etc are stored on a san.
I am looking for advice on how to achieve this.
