I think you will want to leave the old core in if you are doing this
operation.  Most of the time the new slot will overlap the old one by some
amount or be close enough that you risk the thin wall between the slots
coming apart.  Why fill the old slot when it is already filled with a
perfectly good piece of wood.  Just cut off the old knuckle flush to the
bottom of the shank.
