We have a VPS hosting a few of dozen sites at server.example.com. We're deploying 3 more VPSs this week to cope with growth & want to change our naming structure.E.g. s1.example.com, s2.example.com, s3.example.com, etc.If we change the hostname of our current server, is there a way we can set an alias (like a CNAME) so that we don't have to change the config of every device that connects to us for mail services? Currently almost 80 devices.
When changing the hostname of a server, can a CNAME be used with the old name for backwards compatibility?
