Mostly, the biggest changes are going to be skills/CMB/CMD. Every single
feat that grants a skill that Pathfinder does not have, you will need to
reference Paizo's PDF that explains how to convert these and what is the
equivalent in Pathfinder. i.e. Spot/Listen = Perception, Hide=Stealth As
for the grappling rules, I do not know the 3.5 system, but same thing goes
you will need to reference the Paizo PDF to figure out how to change it.
Personally, I would add each book into a folder called pathfinder_conversion
and correct the data a little at a time.
