?>
When I import it I got the save error message for all entities: Creating default object from empty value File /var/www/mig/migration/sites/all/modules/migrate_extras/entity_api.inc, line 227

Answer 1

Try the latest or updated migrate module https://www.drupal.org/project/migrate. I think you were using old one which were having some issues to migrate entities.

Answer 2

Why don't you try with a feed importer (Feeds module) using XPath parser module?. It's really easy, and you can use both an uploaded file or a source URL.
