Replacing 4pm board (polar-edition-shruthi) with a svf board: any things to consider?

the digital board is already there, also the case of course, and the lights ( i think they won´t work with the svf )

or is the control-pcp from the polar-edition different to the standard-controller-pcp

Nope. All Digital boards are the same (within the same revision which should be 0.7).
