While albums, labels and the images themselves will make the cut, they won’t always have one-for-one equivalents. Color labels may pop up as keywords or tags, for example. Aperture’s non-destructive editing also won’t carry over properly — the Photos app will preserve the changes, but you can’t tweak them short of reverting to the original image. You’ll have to remember these changes if you’re digging through your existing library, and you’ll certainly have to rethink your workflow for future photo shoots.
