This is not guaranteed to work, and you need to take special care with mysqldump and mysql options for such migration dumps.

For instance, if a table contains datetime entries '0000-00-00 00:00:00', or duplicate primary keys, it's not necessarily trivial to migrate using the ordinary, safe options for migrating.
