hi,
we need to check this on your site please provide admin credentials and student credential as well
you can send them in a private reply using this option

we never suggest any user to go for such big update on the running site with live users
if you have live users on your site with running course then i suggest you to please first implement the same on the testing site and update the same on running site.
you can create staging/testing site and can perform the update there then apply the changes on your live site
never forgot to take the backup of your live site before making changes.
