I would normally suggest you keep upgrading the distro to Bullseye (11), 
but in your case, I would pause here.

Forget the Unix domain members in the short term, they are the least of 
your worries.

I would upgrade the DC's by adding a new DC on your new VM, once this 
has been joined and is running correctly, I would then transfer all the 
FSMO roles to the new DC.

Now demote every other DC, just leaving your new DC.

Create another VM, but this time use Bullseye and Samba from Debian 
backports, this will get 4.16.6. Repeat the procedure above, until you 
just have a DC running Samba 4.16.6 with all the FSMO roles.

You can now add further DC's and test the Unix domain members, they 
should still work.

You may have to alter how the webapps login, but then you may not.
