I have a number of legacy iPhoto libraries backed up on a hard drive. There are several and most of them are around 20 GB ( I have 3 or 4.) Within the last year I upgraded Photos and pay for the 50GB iCloud storage. When I open one of these legacy libraries I can't share or use any iCloud features. How can I get all my photos in a format that I can access them, back them up, and share them with others? I also have been having some issues in that even my local System Photo library does not seem to upload new photos (photos I directly scan in or add) to ICloud.
