Of course as long as the tickets have not been activated! Just log into your app account and transfer your ticket to your new phone
You can transfer up to two different tickets once in a 90 day period, but you'll only be able to view your ticket on one device at a time. There may also be a short delay between transferring and your ticket being available on another device
12 trip tickets where some journeys have been used can also be transferred, but all remaining tickets will be transferred at once
