Promoting secondary to primary DNS server

[sudhakar]

Hi Kevin,
Thanks a lot for the response.
My secondary DNS server is gets its dynamic updates from the primary, now I
want my secondary DNS server to act as the primary, I'd appreciate if you
can guide on this issue.

Thanks,

Sudhakar

If the zone is not Dynamically-Update-able, it should be as simple as
changing
the zone definition and reloading (or "reconfig"ing followed by reloading
that
particular zone).

If you have Dynamic Update for the zone, then you'll probably want to change
the MNAME field of the SOA record to reflect the new master. You can
actually
update an SOA record through Dynamic Update, but it's a little tricky (from
nsupdate, you need to do an "add", and the serial number of the new record
must
be higher than that of the old record, otherwise the update will be silently
ignored).
