On that note though if you compare the old code to say a water pipe, the old code could be a pipe with tons of duct-tape over every leak and a new pipe could in fact be a good choice. It's not always a great idea to rewrite from scratch but it isn't always the best to keep old code around either.

Basically the point of the article is that you shouldn't act until you are able to distinguish between these two cases.
