Ramps 1.6 drop in for ramps 1.4

Hi I just want to know if Ramps 1.6 is drop in replacement for Ramps 1.4. If any configuration changes is required if I use all other parts same as Lowrider V2 by Ryan. I intend to use dual stop firmware.
Same display, same drivers, and Arduino 2650. Your response would be much appreciated. Thanks.
