I am a long-time Mac user and I am little confused/concerned about my photos with iCloud Photo Library. As of now, I have about (12 years) 300 GB of photos in iPhoto separated into libraries by year. I am sure nothing will happen to them in iPhoto but what if I upgrade to the new Photos app that is supposed to be coming? Will the application try to upload all of my photos to the cloud? Also, what happens to the photos taken with my iPhone when I go above 5 GB? I don't plan on purchasing any more storage space as I currently use another cloud service.
Thanks
