SCORM results deleted after package update

When uploading a SCORM package over a previous one, if the item identifier in the manifest file is different to the one being overwritten then the tracking data for that SCORM package in Moodle is deleted.

It would be better to display a warning to let user knows that privious data will be lost.  In the health field for instance, those data might be used as proof of required certification for some practice. loosing data leads may lead to restriction on using some equipments and ended impact people health. For example, a nurse who completed a course could not use an equipment or a software because the regulation requires to complete the course before using it.

We want to add a warning so the teacher can decide to go forward or not before loosing data.
