Dear Turnitin users, please backup your courses by unchecking the assignments containing Turnitin in the old moodle website. The restore procedure will give you an error related to it if you don't do it.
If you need the assignments, please download them from the old website. If you need them on the new one, please ask your students to re-upload it. This is due to a limitation in the Turnitin functionalities, sorry for any inconvenience.
Again, if you need support, please email firstname.lastname@example.org
