Let's be honest. Most of us still have huge amounts of legacy code we try to ignore. Probably a Monolith we can't get rid of. Code we fear changing either because we're afraid of regressions or because we don't want our name to appear in the next annotate. In this talk I'll present useful techniques for safely refactoring legacy code. These tools will help you refactor pieces of your Monolith into something you can proudly own, and if extracting to a micro-service is what you're aiming for (don't we all?), it'll help you make a smooth transition.
