Windows 2008 SP2 32 bit Domain Controller Migration to Windpws 2016 Domain Controller

    Question

  • Hi All,

    Recently I need to perform migration of my old DC running on 2008 SP2 (32bit) to Windows 2016.

    I have few branches with RODC running on windows 2008 SP2 (32bit) as well.

    Some of my servers still running on windows 2003.

    Here are some of my questions:

    Can a DC on 2008 SP2 be directly migrate to 2016 or it will required to migrate to 2012 R2 first? 

    If my DC migrated to 2012R2/2016, will it be supported by RODC on 2008SP2 ? Do I need to upgrade my branches RODC?

    Any help will be much appreciated.

    Thanks.

    Jackie

  • Hi Jackie,

    start by decommissioning (or upgrading/replacing) your existing Windows Server 2003 DCs, raise the DFL/FFL to Windows Server 2008 and, at that point, you can deploy additional DCs running Windows Server 2016 in your forest.

  • Hi Jackie,
    I think that you need to upgrade windows server 2008 into windows server 2012 firstly, then upgrade to windows server 2016.
    Upgrading RODC depends on the forest/domain function level
    In addition, windows server 2003 is no longer a supported product by Microsoft. So for better user experience, we would suggest you upgrade the operating system to latest version.

  • Hi Marcin,

    Thank you for your suggestion. I did read on few articles about this.

    i will do a lab test on this before proceed further. 

    I think i will perform upgrade to 2012 R2 first due to some old servers still remains in my environment. 

    Appreciate your opinion on this!

    Regards,

    Jackie

  • Hi Wendy,

    Thanks for your reply on this. Sorry for the late reply as i was on another duty lately.

    I am agree with you about upgrade to 2012 first before moving to 2016. I think this will be the safe route to take.

    There are still some old applications which need to run on those old 2003 servers, i am planning to virtualize those old servers in future.

    May i know is there any good article on performing migration from 2008 (32 bit) to 2012 R2 that i can use as reference?

  • Hi,

    As far as I know, in-place upgrades from 32-bit to 64-bit architectures are not supported. Windows Server 2012 R2 is 64-bit. Domain controllers that run 64-bit versions of Windows Server 2008 or Windows Server 2008 R2 can be upgraded to Windows Server 2012. You cannot upgrade domain controllers that run 32-bit versions of Windows Server 2008. To replace them, install domain controllers that run a later version of Windows Server in the domain, and then remove the 32 bit version domain controllers.

    Hence you need to have a fresh Windows Server 2012 R2 machine which you can join to domain and install ADDS Role then promote as additional domain controller, then transfer the FSMO into windows server 2012 R2 DC.
