Can't say what went wrong. It works when I do it. Tho I prefer to do a clean setup on a new Mac.
...The best way to migrate email is to not migrate it at all. Just use the Internet Accounts settings, put your IMAP/Exchange email credentials in and voila. It all syncs.
If you have "on my Mac" email, you can export the "on my Mac" mailboxes as mboxes from the old Apple Mail app and then import them into the new Mail app.
Do it this way and you end up with nice new clean Mail databases.
