This is essentially the old argument over whether it's better to patch old bad code, or whether it's better to rewrite old bad code. I think all of the same responses would apply, i.e., whether or not new problems might be preferable to the existing ones. Since much smarter people than I have written carefully-considered essays on that argument (and without coming to a clear conclusion), I'll just let them speak for me. :-)
