@NunavutBirder@mas.to I moved from #Aperture to #C1Pro a few years ago. C1 said it could apply the equivalent of Aperture edits; in practice results were awful. I then used ApertureExporter, which iterated through the A Library, calling Aperture to apply edits and exporting the results. That worked really well. I kept the unedited originals (raws) offline, but I've only gone back to a couple dozen. I don't think there's a similar tool for LR, but it's possible manually, I guess.
