If you were playing logged into Game Center on the old device you can simply login to the same Game Center account on the new device and then download the Tiny Towers( in this case hayday) app from the App Store. When you open the app and it connects to Game Center, It will attempt to load your latest saved game. Please allow a few minutes for the restore prompt to come up.
