Upgrade Network and Incorporate New Server "Corey Arndt" <coreya[ at ]smcltd.com> 12.07.2007 14:11:40 I am looking to upgrade our network from Windows 2000SP4 to Window 2003. I currently have 2 Win2K DCs that are fairly old/slow (p3 500 mhz 256 meg ram) and I plan on decommissioning these servers as soon as possible. I am purchasing a new server that will become the new DC (along with existing Fileserver). Question. What is the best way to approach this? Should I upgrade my existing DCs/network (temporarily) and then install the New Server onto the 2003 network and then decommission the old servers? Or, can I install the new Server as a 2003 DC and upgrade the network at the same time then decommission the old Win2k Servers without upgrading them? Any other thoughts? We do have a Windows 2000/Exchange 2000 server on the network also (not a dc). FYI...After the network is upgraded it will be merged with another existing Win2k3 network via VPN. Any help is always appreciated. Thank You
