In the /usr/local/directadmin/scripts/ is a script to do this:

ipswap.sh (run it without arguments to see how to use it)

This will change the source ip address (given as parameter) to the destination ip address for all files needed to be changed.

So all your users, httpd, bind etc. will be changed.

One problem It doesn't change the SOA record SERIAL. This way no secondairy nameserver or any other as far as i can think of, will have your new ip address.

So you probably have to change ALL your zonefiles manualy to increment the SERIAL :s

If someone does know how to this automated

Glad to oblige:

# echo "action=rewrite&value=named" >> /usr/local/directadmin/data/task.queue

don't type in that leading "#" mark; it's just there to show you run the command as root.

This is already in the swapip.sh

On mine it didn't execute that part, so the serial wasn't updated. Just a heads up

Did it work for you when you entered it manually?

I believe it's worked for me in the past. If it doesn't update serial numbers then I'll confer with John to have it rewriten so it does.
