Hello, A family member has recently purchased an iPhone 5S to replace a rather ageing iPhone 4. She's asked me to help in the transfer of information from the 4 to the 5S and of course I'm happy to do so. The iPhone 4 is running the latest version of iOS7 and the iPhone 5S has shipped with iOS8 - I can tell this from the box art as it has the Health app on the front. Whenever I've come to setup a new iPhone, I've always made an iCloud backup for one last time on the outgoing handset and then restored this onto the new handset in the initial setup menu. In the past, I've personally gone from a 4 > 5 and then a 5 > 6+, so I've never had an issue with iOS versions being out of sync. Will the fact that the last backup on this iPhone 4 is an iOS7 backup conflict with the fact that the iPhone 5S is running iOS8? I'm trying to make the upgrade to the new handset as seamless as possible for her, so don't really want to be manually importing apps/photos/settings if I don't have to. Hopefully there must be someone else out there that has had experience of going from an iPhone 4 to something running iOS8 to be able to give some advice? Thanks in advance!
