As the IT person for the company, I'm asked to help move data from one iPhone to another, or one iPad to another when staff upgrade. The person may or may not have an iCloud account, and I don't personally even have an Apple device. How can I best perform backups and restores of data with as little issue as possible, while using my PC? Will I need to have their iCloud or any other login information, or could I just plug in a device, use iTunes, choose backup (It seems a requirement may be that each device is named differently to avoid issues?), then plug in the new device and choose restore?
Will I need to deal with authorizing computers or anything else of that nature?
