>But that would then force me to confront what to do my Edited NEF library. I wonder how others have approached the migration?
I switched from a PC to a MAC for PP a year and a half ago. In doing so I went from NX2 to Aperture. I changed from NX2 because it caused so many issues on my iMAC that I just got tired of fighting it.
When I imported into Aperture I used “referenced” files. This allowed me to keep the files in the folders I had setup on the multiple external hard drives I use. I then color-coded all previews that had NX2 edits. Aperture as Lightroom will not display any NX2 edits, so for the NEF’s that I wanted to see the edits I created a JPG and stacked it with the original preview choosing the jpg as the stack view. Since the actual NEFs were on the external drives and not in the Aperture library I could still access them via the PC and NX2. If I wanted to export a JPG from a version within the edited NEF, or review edits I still had that ability. After a little time and practice I can now PP with the same or better results with Aperture as I did with NX2. This now gives me several great options for plug-ins and other software compatible with Aperture that I would never have with NX2.
