Since that fateful day, many many moons ago, when I got my grubby hands on a Slackware 1.19 CD and got hooked on Linux forever, I have never upgraded any version of Linux. Instead I have always saved whatever I needed to preserve, and done a ground-up install of the new version.
However. I am now running Natty on the laptop that currently serves as my main machine (read: I make my living with it and would be sunk without it) and there's so much stuff on it that a ground-up reinstall of the OS and all apps would take a few days (the Internet is terribly slow here in South Africa, which doesn't help either).
I have always been a bit weary of upgrades, but this is the 21st century and things might not be that bad anymore.
What are your experiences with upgrades? I'm looking to go from Natty to Precise Pangolin, because the latter is an LTS version and should sort me out for a few years.
