In the past, my editing process was: I import photos to Aperture, choose which I want to make changes to, make a duplicate copy of the original in Aperture, and then edit the duplicate. They are named version 2, 3, etc. The Version 2's, 3's etc are now my "masters" that i use and have exported to jpg and use to print. Ok well I have upgraded my hard drives and reinstalled Aperture 3. Now all my images are showing as being offline. Again I am using referenced files. Do I really have to go back in and show it where each and every file is? Am I better off starting all over and reimporting every album? If I do this, will I lose all my "masters" I have made. Remember, I made duplicate copies of my images in which I edited and am using "Version 2" as my actual edited image that I am selling.
