If you are going to have more than one AD DC, then using Bind9 makes
sense.

It is not really a case of 'more sense', it is just a different way of
doing things.

If you ran the classicupgrade with '--dns-backend=BIND9_DLZ' then Samba
should have been set up to allow Bind9 to use the DNS info stored in
AD.
You will also need to remove any zones from the named.conf files that
are also in AD.
You will find info on to set up Bind9 for Samba AD here:

If you do decide to use the Samba internal DNS server, then yes, you
will need to stop Bind9. You will also need to remove the 'server
services' line from smb.conf on the DC and add a 'dns forwarder' line.

Then you probably need to follow this:
https://wiki.samba.org/index.php/Configure_DHCP_to_update_DNS_records_with_BIND9

But you will need to get Bind9 working correctly first.
