evolution to thunderbird

i am migrating a user from evolution 3.8.5 to thunderbird. They have quite a lot of folders, and would like to know how to go about moving them into thunderbird? I know evolution changed to maildir and thunderbird uses mbox, so how can this be done?

In my experience the best way to go is to create a new user account, copy Evolution’s folders into it, and test the import. I’ve noticed that users loosing folders when created within the INBOX.

that has just given me an idea. Did not think to try use import export tools in thunderbird. Will give that a try thanks
