Hi Bev
What is required here is to do a course backup in Moodle and then restore the course into a Totara 2.7 site - these systems are compatible. for the backup settings select the face to face activities and user data
Go into the Totara 2.7 site and restore the backed up course into a new course and check this looks Ok.
Upgrade the Totara 2.7 site to Totara 9 and the face to face activity should be upgraded to seminar activity with user data intact.
regards
