I'll concur in my experience. I've upgraded a number of Ubuntu servers
through major version updates. The longest jump I have is on Fedora Server.
One particularly central and critical server was built before I arrived,
with Fedora 18. I have personally upgraded that on every release starting
from 21 on up to the current 30. It's certainly possible to have major
version upgrades be reliable. The big trick is to read release notes for
any software you are using and note any issues they mention.
