Can I keep my all my apps and data on the older iPhone when I transfer everything to the new iphone?

Yes. All of the data on your old iPhone will continue to exist on it even after the transfer has been completed to the new iPhone.

Sure. If you want to be super safe, you could back up the phone as well.....just in case.

I have an iPhone 6s. Does it include the music files? If so, please provide detail steps.
