Moving versions without permissions issues?

Is there any way to move reference movies from one project to another (in this case it’s pencil tests) without having permissions issues for folks that are on the NEW project but weren’t on the old one? We moved pencil tests from a development project to the actual production project, and the new animators (not associated with the development stage) couldn’t play them. They could see they existed, they could scrub the thumbnails, but there was no way for them to launch the movie in the overlay player that we could figure out.

As a fast workaround I just re-uploaded the media to the new project but I’m wondering if there’s any way that the moving only would work.
