Itunes and Icloud have hijacked my contacts
I broke my IPhone 5 and now I am trying migrate my files and contacts to a IPhone 4 I have, but ITunes and ICloud feel the Iphone 4 can.t handle the load, PLEASE How can I fix this error from ITunes, "ITunes could not restore the Iphone 5 because the backup was corrupt or is not compatible with the Iphone 4 that is being restored"? This is a business phone and I need all my customers information today, now its almost Tuesday ,
iPhone 4, iOS 7.1.2, updates from IPhone 5s IOS 11.2
