First leave the company, three junior devs supporting a $20m system isn't realistic. Hey I've done this, everyone states just rewrite each part isn't really helpful. You first need to fixup obvious brokenness, turn on error logging and warnings within fpm, next fix absolute path issues, next fix any containerization issues (deps, etc) and containerized it, next roll out some sort linter and formatter. At this point you have a ci system with standardized formatting and linting now slowly part out things or do a full rewrite as you now can read the code make changes locally
