If you had iCloud Contacts (Settings > [username] > iCloud > Contacts) turned on in your old phone, turn that on in the new one and the the contacts will sync to it.
Or to migrate all of your data, see: Transfer data from your previous iOS device to your new iPhone, iPad, or iPod touch - Apple Support
