[cobalt-users] When you migrate... isn't DNS supposed to migrate too?

["john" <john@xxxxxxxxxxxxx>]

Hmmm...

If I simply use a text editor and delete all the lines out of
/etc/named/records that contain old IP numbers, what happens to the pri. and
sec. files also in the directory?  Do they end up rewriting the
/etc/named/records file later or are they just excess files that can be
deleted later when I have time?

Note - during the migration, some domains were moved to a new server so this
question only applies to domains no longer housed on the server.

..john..

You could also use perl to do this.
Lets say that you you are moving from 10.10.10.0 network to a 192.168.20.0
network.
perl -pi -e 's#10\.10\.10#192\.168\.20#g' /etc/named/records.

or you could use this with a wrapper to re-map indivual ips
perl -pi -e 's#10\.10\.10\.200#192\.168\.20\.10#' /etc/named/records
