How to transfer DNS server to another server?

Question

Domain Name System

Hello, the following problem arose: it is necessary to transfer the DNS server (bind9) to another machine. While all zones are preserved. On a live FreeBSD OS server, the new machine will have Ubuntu Server 14.04. The IP addresses on the new machine will be the same as on the old one. One external and one local IP.
Please tell me how to solve this problem?
Thank you.

Answer 1

1) Transfer the bind'a (named'a) settings to the new machine in /etc/bind
2) Adjust if necessary
3) Turn off the old machine
4) Turn on the new one, give it addresses
5) Check the settings in /etc/default/bind9
AND , in fact, start bind
There should not seem to be any particular problems. You can even write a script for migration.

Answer 2

Shouldn't be a problem, just copy the config files to the new server and you're good to go.

Answer 3

backup the named chroot folder, especially the directories:
etc/ - there should be a named.conf config file
var/named/ - all server zones are there.
This is for linux, didn't work with freebsd, I can't say for sure.
deploy a backup on the new server.
