Nothing can be lost like before

This server runs Ubuntu Linux which uses the time saving apt-get system for system management. A normal system upgrade is this simple (in case you havent tried apt-get):

>>> sudo apt-get update
>>> sudo apt-get upgrade

The apt-get command allows for dist-upgrade which means not only does apt-get upgrade with all security- and features- upgrades, it upgrades to a completely new system .

Upgrading to a completely new system has it's risk, so of course one makes sure one has backup in place. This time things went a little bit wrong with the Zope part of the update. The upgrade of Zope and Plone just didn't work. Since I run this server on VMWare Server which works well thanks to how conservative Linux is with resources, I was in a position where I could just go back to my saved virtual machine and start over from where it all began. No data lost.

I'll get back with more info on the Plone upgrade as soon as I have succeeded. Needles to say, this experience has encouraged me to try again. After all. Nothing can be lost like before.
