Replacing a DC whilst using the same IP's

    Question

  • Hi,

    I'm replacing all Server 2012 R2 domain controllers in my environment with Server 2016. For each domain controller in the existing environment I'm going to create a new 2016 server, add directory services to it (promote), move across FSMO roles etc to it (if there are any), then demote the server 2012R2 domain controller.

    I then want to change the IP of the new 2016 DC to the IP used by the 2012R2 server.

    Are there any special considerations I need to take into a account when changing a 2016 DC's IP addresses?

    Thanks

     Your scenario seems to OK,just run "ipconfig /flushdns" then "ipconfig /registerdns" after change ip of DC.also check from dns records for update correctly.

  • Hi,
    In addition, after you demote windows server 2012R2 dc, you could also do metadata cleanup for the old DC: https://technet.microsoft.com/en-us/library/cc816907(v=ws.10).aspx

    Hi

    Additional info; If a Domain Controller forcefully demote then you should perform metadata cleanup,but if you gracefully demote no need to perform metadata cleanup.
