Step-by-step guide

1. Find course in Publisher Tool and edit and change the seat to Verified

3. Find the course run in course-discovery Django Admin tool here https://prod-edx-discovery.edx.org/admin/course_metadata/courserun/

5. Find course product in E-commerce Oscar dashboard using course title (e.g. Seat in course-title) in product title field here https://ecommerce.edx.org/dashboard/catalogue/, it will return multiple product types
   1. Open product details with type "seat"
   2. Goto variants section and delete the Professional Education variant and save the changes, verify course ID before deleting.
   3. Delete the product with type "Enrollment Code" for professional track as well for that course run otherwise Publisher will raise error on publishing due to mismatching product variant for professional.
6. Goto LMS Django admin tool and find course modes for this run here https://courses-internal.edx.org/admin/course_modes/coursemode/
