Merging Libraries in Photos - changing back to the original System Library
I followed some instructions I found to merge 3 libraries in Photos and I noticed that I lost the albums along the way.
Here's what I did:
Library1 -> make system library -> turn on iCloud
Open Library2 -> make system library -> turn on iCloud
Open Library3 -> make system library -> turn on iCould
This, I think merged the photos from all my libraries into one - which is now Library3.
BUT, I lost all the albums that I wanted from Library1.
I want to make Library1 the System Library again - will iCloud/Photos recognize that all those photos are already in iCould or will it try to upload duplicates?
Thanks!
