Yes, that's correct. You can run samba_upgradedns on any provision and
it should upgrade it to use AD based backend.

DNS partitions do get replicated, but you might have to restart the
secondary DC to get them correctly replicating. There is an issue
regarding msDs-hasMasterNCs attribute, which has yet to be resolved. I
haven't tried to set up a DNS server on a secondary DC using
replicated DNS as yet.

You can use my dns-wip branch. First make sure that the partitions are
getting replicated. Once you confirm that, run samba_dnsupgrade on the
secondary DC to setup a AD database for BIND in dns/ directory.
Finally run BIND with DLZ on secondary DC. Obviously this hasn't been
tested, so your feedback is most welcome. :)
