Migrating from Drupal 7: source database does not contain a recognizable Drupal version After looking at this issue, it appears to be my schema_version. How and what do I need to change about the table to get it recognizable as a Drupal version?
I was able to solve this after putting in the correct prefix.  This issue on drupal.org was very helpful: https://www.drupal.org/node/2637870   

The correct prefix for anyone with a similar problem is shown here: http://i.imgur.com/MKf6CuG.png
