I had at least 5 evolution folders in my old home dirs and backups. This means 5+ addressbooks and 4-5 mail spools. Since I could not find out any better ways, I’ve just moved the .evolution (and even one evolution) folders to a temporary folder, and started to delete unnecessary files and empty dirs. Then I’ve created several empty addressbooks in evolution and just copied the addressbook.db and addressbook.db.summary files into the appropriate dirs. It worked. Now I can move the address cards between them. Well, that will be still some work…
To be continued with mail folders.
