Copying cinematics, shots cameras and camera keyframes from one project to another

I recently completed a successful datasmith import from 3ds max to 4.19.1 I was so proud of myself tweaking materials, creating camera keyframe animations, learning cinematics, building a master sequence with shots, etc. Not great work, but feeling pretty proud.

Of course, this week everything has changed (the building and sculpture model) and I needed to do another datasmith import and be able to run the camera sequences again.

Being a noob, I need a little help getting all of the animated cameras (2) their shot data and the master sequence copied from the original project to the new project.
What would be the best way to proceed?

Thanks in advance! -Jim
