   After added Windows 2019 Server1 as a AD server, he wants to have UAT login, policy and drive testing to force authentication from Windows 10 testing PC to only Server1 (Windows 2019 DC) instead of random authentication from Windows 2012 old DC.

Something here could help.

There are better ways to verify. Using dcdiag, repadmin tools and confirming event logs are free of errors.

Simplest solution may be to just turn off the old domain controller for testing.
