A ten year old system with a basic architecture from a distant past (.NET 1.0? VB6?). New functionality built throughout the years with the then state of the art technology. On top of that some cosmetics to make the web interface look modern, but in reality the application is rotten on the inside and about to fall apart any day. That’s a common work environment for many developers. But there is a way to get out of it without funding for a complete rewrite. Anders shares his experiences on strangling, a method where a new architecture is built in and around the existing code based, gradually replacing the old rotten code with a shiny new architecture.
