I am migrating a DNS system into a Hestiacp cluster, and intend to replace the servers one at a time, by changing the IP addresses of the name servers as registered with the domain registrars.
They will be slaves of a master that will not be used as an authoritative server.
There are about 400 domains involved.
In order to have the servers ready, I am setting them up in advance of the change with temporary hostnames. The first will also change its IP address to the existing IP address.
The things I want to know are:
- Is it possible to rename the remote dns host on the master or would it need to be removed and readded?
- Does changing the hostname affect the API key and does that need to be regenerated?
