A Horcrux is one of the darkest aspects of magic I have ever encountered. In my line of work, that is impressive. Its solution is equally dark. If Potter wants to survive the cleaving of his soul from Voldemort, he must make his own Horcrux. You know the method for achieving this. When his mortal body is destroyed, so too are any soul fragments contained within. We can then resurrect him in a new body, much like Voldemort was resurrected, without the parasitic part of Voldemort's soul."
