Sorry, replied too quickly. My point is that if things are so bad that they warrant a major rewrite, then they are probably so bad that there is no simple way to map the existing data into events or starting conditions. It might be true if you have a simple well defined silo of a system that does one thing well, but not of you have what the author described, a monolith that does several things in the same codebase.
