  • Upgrade current ad (2003) to 2008

    sorry if this is a re-post.

    I have two AD's in my domain (

    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 I first demote the ad using dcpromo, then upgrade to w2k8 r2 standard, I just dcpromo again?

    Are you planning an in place upgrade or a fresh install?
    IMHO better to demote, disjoin domain, format and reinstall, then repromote

    I take it you have upgraded the AD schema already using ADPREP from the R2 media?

      yeah would love to re-format and install clean...but I have backup exec running and I would like to just keep the current backup job going this evening.

      haven't done anything with win2k8 R2, so no on the second part of your question/reply.

      if I can get Symantec to run on another server (win2k3) then I will do a demote, and a fresh install, then promote. Keeping the same server name as well...
