I've just bought a new desktop and installed Ubuntu 12.10 on it. My old desktop has Ubuntu 12.04 with Evolution as the mail client. As Evolution is no longer supported on 12.10 I'm trying to get my Inbox and Sent Items from Evolution onto my new computer such that Thunderbird can read them. So far all the tutorials on the net say to navigate to .evolution/mail/local and copy the Inbox and Sent Items folders from there into the appropriate directory in Thunderbird. Unfortunately I only have an SQLite folders.db file there and not individual Inbox and Sent Items files. How do I get around this?

All help appreciated,
