there are a number of ways to do this
1) a hot air pencil is a good way if you are experienced so as to not to blister the board. i use a weller wmd 3 this is a desolder station with a hot air pencil.
2) the best way is with infra red heat soldering staion with a heater bed.
the heater bed warms the bottom of the pcb and then you use the infra red pencil to warm from the top this then warms the solder under the bga and it is released. to replace you have toprep the board first with solder paste using a mask then place the bga on the board an do the same as for releasing it .
