I have LR 4, and have signed up for the "Photographers Special" CC license which includes LR 5. I have a desire to run Lightroom on 3 machines. I know that I can move the catalog and files from 4 to 5, and since I plan to use LR 4 on a laptop for travel I could probably continue to move them into the LR 5 catalog at the end of the trip. But what if I wanted to move a collection that I had processed in 5 back to 4? would that work?
Thanks,
Alan
