Read firmware from Teensy 3.2

Hi, I have an old application where a Teensy 3.2 is used
Now the module has been damaged, and I would like to buy a new Teensy 3.2 module and copy the firmware to it by reading it from the old module.

The problem is that the Teensy Loader tool seems like it can only write firmware but not read it. So the question is: is there a way to read the firmware from an already programmed Teensy 3.2 and transfer it to a new one? Maybe even using NXP/Freescale tools.
Can anyone help me?
