We have updated the video which explains and shows the process of transferring content from myBU to Brightspace.
In this version we make it more clear that Turnitin boxes should not be exported as these will need to be set up within each unit.
The revised video is available from the Brightspace page of the TEL Toolkit (point 6 of the Brightspace resources list).
The video is just over 6 mins long and well worth a watch.
