Doug ordered a new iPhone 6 Plus. He has his old iPhone 4 backed up. He also has his Samsung phone backed up. He wants to restore the apps he had from his old iPhone, and his calendars and contacts from the Samsung, to the new iPhone 6 Plus.
Leo says backup the iPhone 4 to iTunes and restore it to his new iPhone. Then sync the contacts to Google and log into his Google account on the iPhone 6 Plus. It'll sync and his contacts and calendars will be there.
