What is the workflow/steps to create Students, and do enrollment to a Program in Bulk

I have setup my erpnext education and i would like to add Students, enroll the to a Program in Bulk using the Import Tool. What is the sequence of steps i need to achieve this. Do i start with student Applicants, then import Students or what?

I have figured it out. In the Data Import Tool, you import Student Applicant first and then use the Program Enrollment Tool

How to enter already existing students to the ERPNext system? Should I apply Student Applicant first or is it possible to upload Student in bulk ?

I tried upload students using Data import tool and it gives me an error stating Customer Territory values missing. I had created a separate topic for that but no one has replied for that.
