samba - Nov 2021 - Samba Upgrade

I currently run a small standalone network with REL7 running Samba4.12 
in an AD DC setup.? The REL7 box is also the File Share server.? The 
configuration has been working well for a while, but as previously 
posted when I went to 4.12,I had issues since I need to run in FIPS 
compliance mode.? In a test configuration I setup a REL8 box with Samba 
4.14 again AD DC with file sharing.? It appears to work with the only 
issue I've seen yet is on my windows test client, I needed to use the 
servername to access the share.? The ip would prompt for a username and 
password and never allow access.

So assuming all is well with my new setup, how do I bring in my old 
configuration to the REL8 box?? I can do either offline with copies of 
files or join the new REL8 to the old AD Domain and then decommission 
the old 4.12 box.? Any insights or guides?

The only way to upgrade a DC is to add a new DC running the new version
of Samba and then demote the old DC.
