"Photos and videos stored in iCloud Photo Library will remain on their original iOS 8 devices and will upload to iCloud Photo Library again automatically." I'm a little concerned with this approach. Since I'm currently using iCloud Photo Library, my iPhone no longer has a full-resolution version of all photos. That's one of the advantages of using iCPL -- it saves a tremendous amount of local device storage by only saving a thumbnail and low-res version of the image for everything except recent photos (less than a couple days old). So, if they wipe out the iCloud version and expect my device to transfer the full-size images up again, we're going to have a problem. Anyone have any theories?
