So after moving everything, fixing the bind config and restarting there 
is still an issue. While the forward zone myhome.nurdog.com is working 
fine,  the reverse zone has a problem.

Note that this zone appears to still be pointing at 
nikita.myhome.nurdog.com (should be nureyev.myhome.nurdog.com) as its 
nameserver and the records for Name=10 and Name=11 are missing. 
Something still seems to be broken because if I add the missing entry:

 > samba-tool dns add nureyev.myhome.nurdog.com 1.168.192.in-addr.arpa 
10 PTR sasha.myhome.nurdog.com
Record added successfully

But subsequently:

 > samba-tool dns query nureyev.myhome.nurdog.com 1.168.192.in-addr.arpa

     PTR: rpi3-server-2.myhome.nurdog.com (flags=f0, serial=108, ttl=900)

And still no Name=10 appears. It appears that there is a problem with 
the reverse zone still pointing to something old. Admittedly this 
problem is not so critical but I would like to fix it.
