I have two AD’s in my domain (mydomain.com) 1. adx 2. ady both are Windows 2003 STD, 64 bit with all the current SP’s and updates. I want to upgrade one server (ady) to windows 2008 R2 STD. I’ve already moved all the FMSO roles to ADX, and I’ve also made ADX the DHCP/DNS server so my users can continue to work properly. so basic question…do I first demote the ad using dcpromo, then upgrade to w2k8 r2 standard, I just dcpromo again?
