Before

When upgrading from Drupal 6, the migration system was creating two comment types: comment and comment_no_subject. This could results in conflicts and problems.

After

When upgrading from Drupal 6, the migration system is now creating one comment type per node type: comment_node_{NODE_TYPE}. This is the same behavior as what we have when upgrading from Drupal 7.
