You do not have to switch everything over in one step or ever. The good thing about HAML is that you can mix HAML and ERB in a single project and everything works just fine. If you want, you can gradually convert old ERB templates to HAML or you can just use HAML wherever you want and leave the old ERB code as it is. This way you can try HAML without any risks and see if you like it or not. After the initial learning curve, HAML is really great.
