After a little searching, I found out how to import Evolution 1.4 settings and data in /home/$USER/evolution into 2.2.
All you have to do is go into the Gconf Configuration Tool and change the keys “version” and “last_version” under /app/evolution to 1.4.6. When you start Evolution it will find the folder ~/evolution and ask you if you’d like to import the old data and settings. I believe it over-writes the current settings.
Today I’m updating one of the computers at Sprachenatelier Berlin e.V. from Suse 9.2 using KDE to Ubuntu Hoary 5.04. Hopefully I won’t run into any problems I’ve tested everything i can think of. I’m sure I’ve forgotten something, though.
