Restore From Totara - Moodle 3.9+

Hi All,

I have a problem tryiing to move from a Totara Platform to Moodle with the users intact and all their course enrolments in place.

A simple backup and restore brings all the manually enrolled students across OK but it doesn't bring those enrolled via Totara's "Audience Sync" method. 

Is there a way to:

1) Bring all the users across

OR

2) change them to manual enrolment in Totara to bring them across

Cheers

Dave
