While some people succeed at major version upgrades, the few times I
have attempted it resulted in breakage, frustration, and lots of wasted
time and energy.
Now I backup my configuration settings, remove the old system drive,
take an image of the old system drive, install a new/ zeroed/ secure
erased system drive, do a fresh install, migrate my configuration
settings, and test each subsystem as I go. If everything works, I'm
done. If not, I lower my expectations, find another distribution,
and/or build another computer, and restart from "do a fresh install".
I have reached two conclusions:
1. Upgrading software is the act of replacing an existing,
partially-known set of bugs with a another set of bugs -- some old, some
new, some known, some unknown.
2. Software distributors never fix 100% of their bugs -- they make a
new release, abandon the old release, and declare victory.
