In Moodle, I create a Moodle backup (not an IMS Common Cartridge) and then import it into NEO. It creates the classes, but it doesn't bring over any attachments or resources that I have included in the lessons.
I've tried backing up with both Moodle and IMS Common Cartridge. NEO allows me to import using either format.
Is that just a problem with the NEO software or am I doing something wrong when I create a backup with Moodle?
