That had been my experience, long ago.  After going through that upgrade
hell a few times, I vowed not to do it again.  It *was* much quicker to
backup the few /etc/ configuration files that I had customised, then
modify the new install's configuration in a *similar* manner.  And
"similar manner" are the keywords, some things change between releases,
and old configuration files can cause problems.  Doing upgrades over the
top doesn't mitigate the problem, few applications seem to be written to
read an old configuration file, and update it to the current version.

That's a hell of a lot of downloading, and timewasting, to go through.
Download, start installing, installer grinds gears for ages assessing
what you have already installed, trying to make the upgrade be the same.
And there can easily be some showstopper that's not in the new release,
aborting the install.  Then you have the huge install time.  Do this
several times over.

There's system configuration, system-wide application configuration, and
per-use application configurations, that all have to be taken into
consideration when upgrading.
