[BlueOnyx:18230] Changing Secondary DNS to Primary

[Dr Martyn Bailey]

Hi,
I have a machine with Chris at Virtbiz which currently acts as a
public DNS server.  I have it setup so that the zones are created as
secondary, and the main DNS data is pulled from another machine -
which is no longer accessible, so all DNS records will expire - which
is not 'a good thing'!

Is there an easy way to make the existing secondary records primary records?
