Consider switching to g-mail. You'll never have to transfer anything.
GMail (or Microsoft's cloud based Gmail competitor, Outlook) is so much simpler than all the solutions suggested so far.
Gmail allows one to get all their emails from whatever email address(s) they now have and have one email solution for any and all devices they have or ever get on. Emails, address book, favorites/bookmarks, etc synced to all their devices. And emails/contacts are accessible on any system they might use in any other location. Backup is automatic, a cloud system feature.
There are always those that question the security of the cloud, or "big brother" watching, whatever.
But once you start using an email system like Gmail, you will never go back to a PC based email client. Even if you only have one device (like a PC), the backup alone is worth the move away from a PC based email client. I have had to tell a lot of people with crashed hard drives that their email and contacts were lost.
