I have multiples iOS devices - a 64 GB iPhone 6 Plus, a 128 GB iPhone 6 and a 128 iPhone 6 Plus. I want to combine all the data on all these phones into a single iPhone.
By data, i mean Photos, Mail, Contacts, Calendars, Reminders, Notes, Wallet, iBooks. I have iCloud Sync turned ON, but the data exceeds 5 GB (obviously), so I want to know if there is a way of doing so without the Cloud or via the Internet. Maybe iTunes can help me somehow. I regularly backup my Photos to Microsoft OneDrive and Google Photos, but i doubt if they are the originals as i had captured. Especially, the panorama, hyperlapses and slowmotion videos.
I am also willing to buy a new 256 GB iPhone 7/Plus (if disk space is an issue), but i would prefer to combine the data into an existing device, assuming free space is available or not an issue, how can i achieve that goal?
