What is the best practice for keeping your IPs for DNS servers the same through OS migrations?
The RH articles for migrating from RHEL7/CentOS7 to a newer version of OS want you to do a flatten and reload. Migration basically is install new OS set up a new replica on new server OS. That basically forces a new IP on the new replica, and you decommission the old server. Do you just swap IPs? Can you simply just move the new server to the old decommissioned servers ip? Or do you have to do something special in IPA? We don’t want to change our DNS servers IPs on ever migration to a new OS version. How can we avoid changing it on every OS upgrade essentially? I think the DNS is easier, but in a similar fashion we want to keep “ipa.example.com” what is the best method of keeping that hostname pointed to the entire IPA cluster? Right now it’s an actual machine, which is bad (we know). But how can I set up the DNS to effectively round robin ipa.example.com to all of our ipa servers?
