[ActiveDir] AD Migration Question

[Alborzfard, Alex]

I have a W2K AD that I want to migrate to W2K3 AD. What’s the best option: In-place upgrade of the W2K DC or standing up a brand new W2K3 DC server And then upgrade the W2K DC to W2K3? By the way the W2K DC is also running DNS, DHCP, & WINS. I have one more DNS server. If I go the second route do I need to set up a DNS server or can I use the existing ones?   Thanks   --Alex
