Go to: Settings: Global Import and Restore defaults
- When restoring a past Moodle course into a Moodle course created by the Moderation Portal, use the section "Restore into an existing course" and select the Moodle course that was created by the Moderation Portal.

- In the Settings page, untick “Include enrolled users” and “Include groups and groups” (groups are created by Moderation Portal).

- On the Schema page, we recommend to untick all Turnitin and Assignment activities*. This means you will need to re-create them manually on the new Moodle course.

*This is to avoid that restored Turnitin activities with the IDs of the backed up course,causing Turnitin IDs to double up.
