    Hi guys,

    We have Windows server 2012 standard environment in a virtualized environment. We want to migrate from 2016 to 2019. Ca any one please guide us detailed migration process so we dont lose any data and can smoothly migrate our servers to 2019. We have an isolated setup with exchange and Sharepoint services with many other servers.

    Many Thanks

    That's correct, you'll need to purchase the new server license in order to upgrade.

    The two prerequisites to introducing the first 2019 domain controller are that domain functional level needs to be 2008 or higher and older sysvol FRS replication needs to have been migrated to DFSR
    https://techcommunity.microsoft.com/t5/Storage-at-Microsoft/Streamlined-Migration-of-FRS-to-DFSR-SYSVOL/ba-p/425405

    I'd use dcdiag / repadmin tools to verify health correcting all errors found before starting. Then stand up the new 2019, 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 again verify health, when all is good you can decommission / demote old one, and move on to next one.

    I'd also reach out to other technology experts in dedicated forums over here.

    Hello,

    Thank you for posting in our TechNet forum.

    It is suggested that we check our AD health before we make any change in our AD environment.

    As Dave mentioned, the minimum requirement to add a Windows Server 2019 Domain Controller is a Windows Server 2008 functional level. The domain also has to use DFS-R as the engine to replicate SYSVOL. So before we add 2019 DC to the existing domain, we need to ensure the functional level is at least Windows Server 2008, and the SYSVOL folder replication type is DFSR.

    For more information, we could refer to: https://docs.microsoft.com/en-us/windows-server/identity/ad-ds/active-directory-functional-levels

    Here are the steps about how to add a new DC to existing domain. We can try the above steps.

    1, Check DC health by running Dcdiag /v and check AD replication by running repadmin/showrepl and repadmin /replsum.
    2, Join Windows Server 2019 to existing domain.
    3, Promote Windows Server 2019 as Domain Controller.
    4, Repeat step1 to check AD environment health.
    5, Transfer FSMO roles to the new DC if needed.
    6, Demote the old DC if needed.

    As for the concern about Exchange and Sharepoint, we could turn to the dedicated forums. Thank Dave for the provided links of the forums. 

    For any question, please feel free to contact us.


    Best regards,

    Thanks Dave for your detailed response. Actually, we do have sharepoint and exchange (2016) servers running in this environment and also have SQL Server 2016 in cluster mode. Beside of all this we do have many other servers around 30 which we don't think is the best idea to migrate them all. How if we simply do an in place upgrade using 2016 ISO so we dont lose any data, roles services assigned to the servers.

    We already have licenses for our 2012 standard servers which are running, which we believe is enough for in place upgrade to 2016 standard. Otherwise we would require licenses for 2016 standard if we go for migration option on different servers. Is that correct? Please advice.

    Many Thanks

    Regards

    Ali

    Yes, regardless of method you'll need to license them for the new operating system. An in-place upgrade is very risky for a number of reasons. As to upgrading the other technologies I'd reach out to subject matter experts in dedicated forums located here.

    Dear Dave,

    We have 2012 R2 DataCenter license, can we upgrade this to 2016/2019 datacenter edition with the same key we have? when we are trying to upgrade from windows 2016 ISO downloaded from microsoft, it is giving option to clean up everything (which we dont want) because it is an evaluation version. Please advice how we can do inplace upgrade using same 2012R2 key?

    Thanks

    Your 2012 R2 product key is specific to Server 2012 R2. In order to upgrade or otherwise install Server 2016 or Server 2019 you'll need to obtain a product key for that specific operation system and version.

    You mean we must have to purchase 2016/2019 key before we either upgrade or reinstall the servers? Actually we upgraded our windows7 pro PCs to Windows10 for free that why asked this question whether it is possible in server case?

    Thanks
