We have 2 domain controllers with Windows Server 2003 Standard edition 32 bits. We want to change those servers with 2 virtual Windows Server 2008 R2 (64 bits). We believe wecannot perform the in place update because we are going from 32 to 64 bits. We are planning in creating 2 new servers and move everythng AD, DNS,DHCP, print server role etc. COuld somebody give us a path to follow? We never have done anything similar. What is especially confusing is that all our DNS resides on the main DC, if we need to eliminate it when do we change the IP address of the new ones? Any help would be greatly appreciated.
