OK. So here's what I did. I got these instructions from the How to restore Evolution thread.
Migrating email from Evolution 1.4 to 2.0 (FC3):
This took a while to figure out, but this post is the essence of it:
* Shutdown any running evolution processes.
$ evolution-2.0 --force-shutdown
* Edit the GConf keys /apps/evolution/version and last_version to read
"1.4.0". You can use gconf-editor or the command line interface:
$ gconftool-2 --set /apps/evolution/version --type string "1.4.0"
$ gconftool-2 --set /apps/evolution/last_version --type string "1.4.0"
* Remove (do you have a backup?) or rename (as shown) the new hidden
$ mv ~/.evolution ~/old-evolution-2.0.0
* Then run Evolution 2.0.0 and it should migrate your 1.4.x data again.
Lean back and have a good cup of coffee, beer, whatever... :-)
Reset both GConf keys to "2.0.0", if not already done. AFAIK
last_version will not be reset.
All of this is way too painful. I don't mind so much, since I am fairly comfortable now in Linux and I like command line tools just fine; however, we really need to move beyond this if we're going to spread to large number of desktops in the world.
Anyway, I hope this helps someone out there.
Best of Luck!
