I once worked on a project that was auto converted from VB6 -> C#. Amazingly it compiled and parts of it actually ran. We still rewrote the entire thing, line by line and then spent months refactoring it. It was our only choice really, so much of the original code was so unclear and all the original developers had left so it was our only hope of keeping the business logic intact.
