<p>That was my first thought, but stopping the secondary would
affect all of the published zones. <br>
</p>
<p>If retransfer ignores serial number, then using "rndc retransfer"
would affect only the specifically-named zone in the
specifically-named view. Resolution of the other zones, in all of
the other views, would be uninterrupted.<br>

<div>Why so complicated? Stop the secondary, purge the zone files
and journal, and start the secondary. The zones will get
retransfered as there’s no state now.<br>

<p>Assumptions: A primary and several secondaries, with the

<p>Scenario: Make a change in the serial number algorithm
which will result in newer zone-data being published on an
"earlier" serial number.</p>
<p>The 'correct' method is to increase the serial number
(by steps not exceeding 0x7FFFFFFF) until it rolls back
around to the desired number. These increments are to
happen no more frequently than the refresh interval
specified in the SOA record. This 'correct' method relies
on nothing more than the communication standards defined
in RFC.</p>
<p>But if we add the assumption: All authorities are running
ISC BIND software, and all are under central management.</p>
<p>can the whole process be reduced to publishing the new
serial number on the primary, and using an "rndc
retransfer" on each secondary?</p>
<p>The man-file says "retransfer . . . This command
retransfers the given secondary zone from the primary
server."</p>
<p>It doesn't say serial number is considered, nor does it
does it say that it is ignored. I'm thinking it makes
sense that it ignores the serial number, but I can't think
of a good way to test this.</p>
