I am clicking on "configure" under Modules > Migrate UI and it is just taking me to
admin/content. According to the migrate_d2d module page, the migrate module should have a dashboard.
Enabling the migrate_d2d_ui module will add an "Import from Drupal" subtab to the Migrate dashboard
I made sure to give the admin user permissions to use the module and I cleared the caches.
I am using Drupal 7.50 on the site I am migrating data from and 7.54 on the new site.
