Upload code from pic

Hello,
For my hobby Im doing some programing in Picmicro, mostly Pic16F87XA, Pic18FXX2.
To do so Im using mplab and Pickit3.

I have an old controll board of airconditioner with mcu Pic16F72.
My question is,
Is it Possible To read the code? and how to do so (upload the code to Mplab)?

Thanks alot
