We removed the old caulk in places and in other places we just taped over it. I don't think it matters much, but might look a little better if you remove the old caulk.

You could probably tape over it (Eternabond is amazing stuff), but will a putty knife or a sander remove the old caulk (hard white stuff)? If the surface is smooth, you will get a much better bond and it will look better after it is done.
