If you have links to recordings in platforms that will be retired (i.e. Echo 360, Kaltura, and TechSmith Relay), then the links should be changed to Panopto links after the content has been migrated into Panopto.
Dartmouth's Learning Design and Technology team recommends creating all new content beyond the Fall ‘20 term in Panopto. The team recommends switching over to Panopto for your media needs for Winter ‘21 and beyond.
