I set-up and synced an iPhone on one computer. That computer therefore has a backup of the iPhone. Unfortunately the iPhone was destroyed and so I have a new iPhone to set up. However I would like to control this new iPhone from another computer. If I restore the backup from the old computer that computer will take charge of the iPhone, which is not desirable.
Is there a way to transfer the backup file(s) to the new computer and set-up the new iPhone from that computer, using the backup? In other words, is there the equivalemt of Migration Assistant for the iPhone? I realise that authorisations will be needed for some videos, music and apps.
