I know there are a million questions on converting iPhoto libraries to Aperture. I am also aware that with the latest versions, there is a commonality between the two. However, I (think) I understand that an Aperture library is significantly smaller as it does not duplicate photos on edits (non-destructive editing).
Assuming that above is correct, is there a way to take an existing (current) iPhoto library and convert it to an Aperture library such that all edited photos are “unified” into a single original photo along the Aperture differential edit file? I'm looking to save disk space.
