Don't own nor maintain any Mac so can't tell anything about it's upgrade
ability.

Couple of times I upgraded Win2000 to WinXP and once even WinXP to
Vista. It can be done but not advisable. But the customer did insist to
upgrade (after my explanations why not to), who am I to disagree.

I personally use Linux daily since about 2003 and Ubuntu since version
6.10. It almost always upgraded without remarkable issues. And this is
applicable to upgrade from 10.10 to 11.4 as well.

Surely, for safer feeling I'm holding UserData (/home for Linux and
MyDocuments on Windows) in separate partition and all the customer
installs I'm doing follow the same pattern. System and Data are *always*
separated.

I only made clean install twice on my personal computer since 2006. Once
after I bought new computer and second time after a successful upgrade
to Ubuntu 11.10, since the system got bloated with exessive libraries
and settings for programs long times uninstalled, and python versions,
and GTK themes, etc. I even cleaned up my $HOME after upgrade, but there
was no real *need* to do this, I just wanted and found the moment
proper.

And let it be mentioned, that upgrades done to our servers running
Debian, have been sound as well. Since at least Etch.

So, definitely there are configurations and occassions, where upgrade
does not work (despite the operating system), but looking at the big
picture, I wouldn't dare to say that upgrade mechanism in Ubuntu or in
Debian are broken and do not work. They do work. The upgrade can be more
sophisticated with smaller footrpint surely, but it still works quite
well.
