DC upgrade

    Domanda

  • Hi,

    We have three Windows 2008 R2 DC. We plan to upgrade to Windows 2016. Can someone provide me with the step-by-step upgrade instructions? also like check list?

    Another question is if I should wait until 2016 R2 release to upgrade?

    Please advise!

    Thanks in advance!

  • There will be no Server 2016 R2

    I'd use dcdiag / repadmin tools to verify health correcting all errors found before starting. Then I'd stand up the new 2016, patch it fully, license it, join existing domain, add active directory domain services, promote it also making it a GC (recommended), transfer FSMO roles over (optional), transfer pdc emulator role (optional), use dcdiag / repadmin tools to verify health, when all is good you can decommission / demote old one and move on to next one.

  • Hi Grace,

    Besides the Active directory service, is there any others roles on your server 2008r2?

    According to the Microsoft, it doesn't support  upgrade in place directly from Windows Server 2008R2 Windows Server 2016.

    https://docs.microsoft.com/en-us/windows-server/identity/ad-ds/deploy/upgrade-domain-controllers

    As  a workaround, we can build a new Windows Server 2016 Domain Controller in the domain and the active directory will migrate automatically to Windows Server 2016.

    In short;

    - Join Server 2016 to existing domain

    - Then promote Server 2016 as Domain Controller

    - Then transfer fsmo roles to new Server 2016 DC.

    - and add second server 2016 with same procedure.

    When these steps will OK,  then  you can demote old server 2008R2 DC   from domain.

    Best Regards,

    Mary

  • DNS would be an integrated part of adding active directory domain services role to your new server. For DHCP migration you can follow along here.

  • Hi Dave,

    Microsoft usually releases R2 2 years after. So I assume it would be this year. Do you know if MS has plan to release 2016 R2 this year?

    Thanks,


    Grace

  • Hi Mary,

    Thank you for your reply. 

    Besides DC, they are also DHCP and DNS server. I need to move this two services to the new 2016 DC too. Do you have instructions?

    Thanks,


    Grace

  • There won't be an "R2" version of Server 2016. They have moved to either a Long-Term Servicing Channel or Semi-Annual Channel releases. Also note Server 2019 may release later this year.

  • Thank you Dave! It's hard to make decision. Should we wait for 2019 or upgrade to 2016? 

    Thanks,


    Grace

  • I guess it depends on current needs. If you're ready to do now then I'd go for Server 2016. Standing up domain controllers can be done in minutes these days (aside from patching) so it will be an easy task down the road to implement Server 2019 if needed.
