After 40 years of upgrading many different operating systems, Windows (from 3.1 to 10), CentOS 6 to 8, Ubuntu, Fedora, Red Hat, AT&T Unix, VAX VMS; I have never observed an upgrade from one major version to the next to work. The last one I tried using their "upgrade process" was Ubuntu 18 to 19. Didn't work.
OpenSUSE Leap upgrades from one major version to the next work fine, provided you know what you're doing.

In the past, I also performed major upgrades on Slackware servers, which were always perfectly documented by the distributor and worked without drama.
