I am going from Drupal 7.6 to 8.6 using the migration UI (https://www.drupal.org/docs/8/upgrade/upgrade-using-drush). When I get to /upgrade/review it lists out the modules that need upgrading.
The issue that, in a new blank website of Drupal 8, I have Drupal 8 modules (like views_slideshow via https://www.drupal.org/project/views_slideshow/releases/8.x-4.6) installed and enabled. However, on the review page, it still shows Not upgraded. My path for the module is modules/contrib. I even tried to move this to the modules directory with no avail. I have tried upgraded multiple modules but they are all said not to be upgraded. Any direction would be helpful!
