How to transfer data from iphone 4 to iphone 6 plus?

I need to move my stuff from my old iphone 4 to my new iphone 6+. The genii at the Sprint store couldn't do it and my 4 is too old & dumb to do it via the cloud. Is the WonderShare TunesGo free tool safe and effective? Does it move your notes & reminders or just pix & music?

You could do so through iTunes. Backup the 4 & restore from that backup on the 6 Plus. That should move everything.
