Uploading multiple Photos libraries to iCloud
We’ve got a number of Photos libraries on a drive (converted from old iPhoto libraries) which pre-date our iCloud.
Is is there anyway that we can upload them to iCloud so they’re visible across all our devices alongside all our other photos? I don’t want to add them all to our MacBook as it’ll need more space that we have on the drive.
All assistance greatly received
