Having Trouble Updating Server From Debian 10

server’s hostname and IP address may change and cause the client email issues when copying the system over from a different server.

Yep, that why I got a reserved IP ($3 p/m) with them so if I move to a new server and I can keep the same IP.
I made sure it had a good reputation as well.
