IP change and named
Sorry, I tend to be annoing sometimes.
I'm in a situation where I have to change my production server's IP addresses.
I host lots of sites and have lots of zones in my server. So I can't just change their IP's from ISPConfig frontend.
My biggest concern is named. I know that I can run update queries on all tables that contain IP addresses and then go and change with sed or perl all the IP's in all config files all over the server. But what happens to the serials in zone files? They will be the same.
Any advice from a person with experience in that will be appreciated.
