Copying Evolution emails from Ubuntu 10.10 to 12.10

The Evolution data structure has changed quite a lot -- the directory .evolution is no longer used. If you made a backup from within Evolution before upgrading, you should be able to restore it (hopefully). Otherwise it will be a bit troublesome:

E-Mail accounts are faster to re-configure (if you used IMAP, data is still on the server. People using POP3 will not have this option to regain their mails).

Other options can be found in several questions on this site, e.g.:

• Evolution data migration (on update) missed all but the first “accounts” (mail, addressbook, calendar…)
• Questions containing '[evolution] migration'

Basically, Evolution currently stores its configuration in 3 different folders:

• .local/share/evolution
• .local/config/evolution
• .gconf/apps/evolution

But not only the location has changed, formats are also different (e.g. address books now use SQLite databases).
