Migrating windows 2008 domain controller to 2016 Domain Controller

Hi,   I am planning to migrate windows 2008 domain controller to windows 2016 Domain Controller. May I know the steps migrate ? Before migrating to 2016 DC do I have to migrate FRS to DFSR ?   ...

    HiVishwa10 

     

    Please advise if you would like to do a clean-install on a different server or migrate on the same server (In-place Upgrade)? 

     

    Firstly, when replacing / Migrating a DC, I would always like to make the new DC have the same IP as the old DC. It simplifies many things, like DHCP scopes, DHCP relays, and devices with static IP. You can give the old DC a new IP and then give the new DC the original IP address.

     

    Thank you,

    Dav,

Should not be a problem but do not do an in-place upgrade. In-place are risky and possibilities of corruption carry-forward. Server 2016 still works with older FRS technology.

I'd check that domain functional level is at least 2003, then use dcdiag / repadmin tools to verify health correcting all errors found before starting. Then 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, transfer pdc emulator role, use dcdiag / repadmin tools to verify health, when all is good you can decommission / demote old one and move on to next one. Also at some point either before or after I'd recommend migrating sysvol replication from older FRS technology to DFSR.

    During FRS-DFSR Migration @ Prepared state when I run Propagation test.I get below error.

     

    "Replication group Domain System Volume,replicated folder SYSVOL Share on member ABCD.EFG.COM

    A new propagation test file cannot be created.Cannot open propagation test folder under replicated folder.The network name cannot be found"

     

    My DNS is not running on windows.

     

    Thank you

      Please run;
      • Dcdiag /v /c /d /e /s:%computername% >c:\dcdiag.log
      • repadmin /showrepl >C:\repl.txt
      • ipconfig /all > C:\dc1.txt
      • ipconfig /all > C:\dc2.txt

        then put text files up on OneDrive and share a link.
