I've used the "strangler" pattern for similar projects - for Javascript, Java and .NET. Essentially, this pattern aims to create a parallel system that functions along side the existing system, which slowly takes over the responsibilities of the legacy system. This way, if you architect and develop your new system correctly, will leave you with solid code and a good foundation, while at the same time, demoting the legacy software to eventual deprecation. So, next time you are looking to fix a particularly heinous defect, a deep cut perhaps, think about starting a new system from scratch that will JUST do what you want the legacy system to do, but, do it more efficiently, with a design for the future. And then start strangling.
