With most modern flat decked skis its generally possible to change the binding system by removing the old binding and mounting (drilling and screwing) a new binding system onto the ski deck. This of course puts more holes into your ski but this isn't a problem as long as there is at least 5mm in between the holes, any less than this risks weakening the screw pull strength and increasing the chance of snapping a ski. Sometimes its necessary to mount the new binding a small distance forward or backward in order to get sufficient distance between the old and new holes.
In some circumstances its not possible to mount new bindings onto certain skis. If the ski has had several bindings mounted on it already it might not be possible to squeeze a new set of holes in. Skis that have a 'rail' system where a moulded ski top deck integrates with a binding system are often impossible to mount new bindings upon. Like wise some skis have deck mouldings front and back which can prevent certain bindings from being mounted in the correct position.
