Important: Please if possible make your ticket private and attach a copy of your database that you try to import.

Description of my issue: I have imported the Drupal 7 Database Dump which was provided by the clients previous host. We are migrating them into Joomla but the table have no prefix when imported. Is there still a way for us to do this migration? Is there a way to add a prefix easily to these records with no prefix?
