    Is there anything else running on the server? Is it your only server?

    Essentially, you would need a second DC in place to take the strain in case anything goes wrong. Lots of research - do you need to migrate services, applications etc - will they run under the new OS or will they need to be updated/upgraded etc. Is your existing hardware suitable?

      If you have a choice, go for a fresh install and move things over gracefully - upgrading always leaves a heap of legacy c**p behind

        Hi blood,the server is not the only server and it has AD DHCP and Dns roles enabled in it and it is not our PDC and BDC

          Hi Ossian, sounds like a good idea with the release date for Windows 2016 due this month and 2008 on verge of being phase out...But if you had a choice would that really be your first option?just trying to be sure...Thanks

            2016 is brand new, so maybe 2012R2 is a more stable OS

            The fresh install (of any OS) involves new hardware (if possible) or a new VM, or at least formatting / clearing the drives that had the old OS. It is preferable to an in-place upgrade where you install the new OS over the old one, leaving traces of the old OS behind
