Import Projects from a previous CourseEdition
This issue is being solved by MR https://gitlab.ewi.tudelft.nl/eip/bepsys/bepsys2/merge_requests/239.
It should be possible for the admin to move all untaken projects (i.e. having no approved group) from one course edition to another. Involved companies should be notified of the fact that their projects are now available as part of a new course edition.
