We've just upgraded from Moodle 2.5 to 2.9 and have some legacy assignments still in 2.2, which we now have to upgrade. We ran the assignment upgrader which seemed to work for a small number of assignments, but when assignments had large numbers of submissions, not all the information came across. Specifically, we are losing the "Last modified (Grade)" data, so we can't tell when the assignments were marked.
Any ideas on how to solve this?
