Hello,
I woul’d like to know more about premium extension.
1/ Original SLUG are same as drupal alias in article import ?
2/ There is any way to keep drupal node id same as worpdress article id ? Same for comment ?
3/ In BBpress, in Drupal, comment on topic is a comment in in database. In wordpres bbpress extension, comment on topic is a topic. Does Your addon preserve redirection from Drupal comment to wordpress topic ?
Thanks
