Talk:Backup 1.9 conversion for developers
From MoodleDocs
I did a M1.9 to M2 backup script for the referentiel non standard module referentiel (http://moodle.org/mod/data/view.php?d=13&rid=2488&filter=1) Everithing works fine but ... user data are not restored at all.
It seams that not any module can restore user data from M1.9 backup. Why ?
