    Good advice, but not an answer. Commented Dec 4, 2015 at 2:15
  • And funny, the artice you linked is basically a rant about how hard it is to rewrite a non-tdd-style code. "Those are bug fixes" that no one is aware about and there are no regression tests for them, so they are likely to reappear, or are now obsolete like the client configuration they target.

    The only detail on the rewrite is that it is "unmaintainable", either the OP forgot what he did and is redoing it, or he is maintaining someone else's code. Either way, the article covers why rewriting is not a solution to the correct problem, because the problems were never identified. Commented Dec 4, 2015 at 2:25
