@atpfm Unfortunately, I have the occasion to actually use backups of my photos. My wife recently passed away, and she was the keeper of the photos. I'm at the stage of things where I’m starting to at least think about dealing with low priority loose ends.

What's the best way to "merge" or consolidate photo libraries? I think I want to move everything into my library, preferably preserving as much metadata as possible. #askatp

@duffbeer703 I think making an iCloud Shared Library and then using it as a midway point to transfer everything from one library to another might work well. Try it with a handful of photos first to see.

@siracusa Thank you John! This works really well - I had forgotten about this option.

The only annoyance so far is that the the locations of the photos aren't enumerated in the iOS UI until you “enumerate" the photo by clicking on the info button. Doesn't scale well to 100k photos :)

That said, it's a minor annoyance that I can live with. Thank you!
