I decided to separate (for the future) my Aperture Libraries into ‘Years’. Not only does this make more sense from an organizational standpoint, but it now immediately cuts my Library from over 72 GB to less than 15 GB. So, I followed the protocol in creating a new Aperture Library 2015 by selecting the 2015 Projects in my original library and ‘exporting to new Aperture Library’. After doing this I notices that while the new library works just fine, the old library still has the same projects there with the previews. Is this normal or should the projects have completely moved over to the new library? Thanks for any help.
