Hi, we were planning to migrate or upgrade our current Active Directory (WS 2012 R2 Std) to Active Directory (WS2019).

I saw several links/guides to do this, but I'm a bit confused on what is the correct way of doing it. So im creating my own thread.

Also highlighting that, once we have successfully migrated the existing AD to the new one, we are planning to have the same Hostname, IP and specially Domain Name. -- The reason for this as there are some applications that points to that Hostname, some are IP.

Hope i can get an absolute answer for this.

Thank you everyone!

    Renaming a domain controller is possible to do but very risky. Better option is to clean up this dependency unless there are multiple domain controllers. Re-iping the domain controller is not a problem to do after deployment.

    The two prerequisites to introducing the first 2019 or 2022 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

    I'd use dcdiag / repadmin tools to verify health correcting all errors found before starting any operations. Then stand up the new 2019 or 2022, 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.
