There are some things you didn't mention. Most imporantly, how will you
change the zonefiles? Through editing of the files on disk? If your zones
handle dynamic updates (for example, through the nsupdate command) I would
have scripted something.
Personally, I'd probably write a Perl script using the Net::DNS module to
AXFR a zone, look for the records that need updating and then do dynamic
updates to update it. One advantage to this approach is that you won't have
to update the serial number - the dynamic update process will take care of
that.
