Change A4988 stepper driver by DRV8825 ones.

I built my own 3d printer and it works fine. I use the Prusa as a model.
Now I have a simple problem, but that I am not able to solve.

Sorry for the noob question, but in "Configuration.h", which lines should I edit to change the A4988 stepdrivers I got in X and Y axes to the new ones, DRV8825?
Are there any changes to be made to eeprom as well?
Thanks!!

    The main difference is the new driver have to be fitted rotated 180deg from the A4988,(so the pot is opposite end)
    The DRV8825s with the 3 micro stepping jumpers fitted will have 1/32 microstepping so you will need to double your steps/mm in config or eeprom.
