In this video we explain and demonstrate how to migrate Active Directory from Server 2012 to Server 2022, move the FSMO roles and upgrade the Domain and Forest Functional Levels.

Note that over the years we have done many in-place upgrades to Domain Controllers at smaller customers but it is a gamble that Microsoft does not recommend.

There are 6 key steps to the process:

  1. Install a fresh Windows Server 2022 (or Server 2019 or 2016) and join it to the existing Domain
  2. Patch, update and power cycle everything you can
  3. Add Active Directory to the new Server 2022
  4. Move FSMO‘s from the older Server 2012 to the new Windows Server 2022
  5. Update DNS in DHCP and statics then demote old Windows  Server 2012
  6. Upgrade the Domain and Forest Functional Level

Like this scenario, I am going from 08 R2 to 2022…. I have read a bunch about problems migrating SYSVOL from frs to DFSR. Are there more steps than shown in this video? Or can this process work migrating content from old to new with out blowing up sysvol?

    Not that I am aware of. DFS died with Server 08 but it kept running if you already had it in place.

    I did a bit of research and found only 1 comment I thought was useful:

    Run “repadmin /syncall” after the dfsrmig commands to speed up things a bit.
