i have an old iphone 5 and want to transfer everything to my new phone 11 but have not got a clue where to start
eay way to transfer everything from iphone 5 to iphone 11
Question marked as
Start here:
Transfer data from your previous iOS device to your new iPhone, iPad, or iPod touch - Apple Support
You can't use quick start because your iPhone 5 is to old, but iCloud or computer backup should work fine.
Good luck!
