Best Practice For Migrating Entire Office To New Subnet Active Directory

    Question

  • Hi,

    I have a scenario one branch office is planning to migrate new subnet. 

    • The organisation is using class A network 10.x.x.x.
    • The brand office exiting subnet is 10.29.x.x/16 and planning to migrate to 10.39.x.x/16.
    • Branch office is under same AD as organisation example.com and will remain the same example.com after migration.

    The reason to migrate new subnet is exiting network infrastructure combine all devices inside /16 subnet, so divide into sub subnets each department with new subnet 10.39.x.x/24. The entire branch office will be inside 10.39.x.x/16 with sub subnets of 10.39.x.x/24 after migration.

    Please advise below questions or good ideas.

    1. What is the possibility to do the migration with less effort?
    2. Do you suggest to build a new DC or migrate the exiting DC to new subnet?
    3. Is there any best practice relating with this kind of scenario?

    Really appreciate your advise and idea...

  • What is the possibility to do the migration with less effort?  >>> You can change client computers ip & subnet's from dhcp.Also you can search a script for server side.

    Do you suggest to build a new DC or migrate the exiting DC to new subnet?  >>> You don't need to build new DC,you can change static ip of a Domain Controller,Check the article;
