Virtual Windows Server 2008 R2 Additional Domain Controller Upgrade Help
Do not in-place upgrade them. The much simpler / clean method is to use dcdiag / repadmin tools to verify health correcting all errors found before starting. Then stand up the new guest, 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.
If 2019 were the target OS, then the two prerequisites to introducing the first 2019 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

- Hello Dave.
I also want this kind of method of migrating path because it is convenient. but honestly, I don't know how to setup. like running the new guest on our server. I have some ideas in my mind on how to deploy the new guest on the server and somehow join in the domain. but firstly, will I need to go to our console or physical server to deploy there the new guest?These may help you get started. If you've never done this then I'd suggest starting with a test environment or find someone to help you with it.
- Hello Dave,
I already found out that our domain controller is installed in ESXi. I logged in using vSphere Client. can I tell that using this will be my test environment?
