Inplace upgrade Windows 2012 DC to Windows 2012 R2 RRS feed

  • Question

  • Hi
    We plan to upgrade some of our DCs from Windows 2012 to Windows 2012 R2.

    Theese DCs is on a DMZ holding our virtual machines management servers so they are not the most critical DCs but they are critical enough to not working for a longer time.

    Normally we dont do inplace upgrade but this is more of quick solution to raise the servers to the same OS level

    So has anyone done an inplace upgrade from 2012 to 2012 R2 on domain controllers? Any problems?

    We have two DCs, in differents locations.

    BR

  • No we literally just upgraded one of the existing servers in situ, let it reboot, checked everything worked and the upgraded box was correctly serving requests and then upgraded the other AD server on another occasion.

  • Yes, we've upgraded some of our DC's from Server 2012 to Server 2012 R2 without any issues at all. Obviously you want to do them one at a time, but we found it completely straight forward.

    In fact, if it wasn't for some unrelated legacy issues at one site (old servers preventing us upgrading that sites DPM install as DPM 2012 R2 doesn't support them, but DPM 2012 doesn't support Server 2012 R2) we'd have upgraded all our DCs by now.

  • Nice  :)

    Did you moved the roles before or did you just upgrade?

  • Very useful information about DPM. We also use DPM, but the issue you mentioned never occurred to me. Thank you for the heads-up!
