Solid advice. I did 2 full re-writes with great success and to add to this list I would also make sure you are communicating with executives (possibly gently at first depending on the situation), really learning about the domain and the requirements (it takes time to understand the application), investing in your team (or changing resources - caution not right away and at once since there is a knowledge gap here). The rewrite will basically have massive benefits to the business: in our case: stability (less bugs), capability to add new features faster and cheaper, scalability, better user experience etc. This can get exiting to executives depending on the lifecycle of the company. Getting them exited and behind is one of the core tasks. Dont embark on this right away as you need more information, but this will matter.
