Just for interest sake. Our upgrade process is less than perfect.

Normally, I do new installs rather than upgrade. It means for sure I have
gotten rid of old stuff.

But I was testing upgrades and thought I would share what I found. First
off I was using UbuntuStudio. I was looking for things like metas not
being included and yes that was so. I also found the generic kernel was
getting dragged in as well as the low latency kernel. (actually that was
what I set out to test)

Anyway, I have an older machine and video card and have had some problems
running some applications like Mixxx for example. It was suggested to me
that I probably had problems even playing videos smoothly too. As happens
I was testing Studio Metas installed on top of kubuntu. And was playing a
video and it looked just fine. This was a fresh kubuntu install. when I
tried the same thing with the updated (from 12.04 to 13.10) the video was
skippy, jittery, not good at all. But on a fresh ubuntustudio install it
was fine. Same video, same player, same kernel, same (supposedly) distro.

The audio which was going through pulse->jack at 48000 and p64, was fine,
not xruns or other artifacts.

So, fresh installs are still the best, no change from 1995.

Really, Hard drives are cheap. One of the least expensive bits one can
buy. Better to put a second drive in the machine, put a new install (or
better try three or four to see which works best with your HW/work habits)
and copy your old home (or parts of it) over... or just put symbolic links

Or, shrink a partition and load the new version in a small partition and
link to the old home. This may be the only way with a laptop.
