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?
Just wanted to update this. Turns out that the main problem with Assignment 2.2 upgrade is that once upgraded, the upgrader automatically submits all assignments, even drafts.
Has anyone else experienced this?
