If the old system is exceeding uptime SLAs, meeting all business needs, and coming in under the budget for such an investigation (it sounds like the total operations budget was less than 10% of one engineer's time), then why bother?

I don’t know the situation, not touching it may have been optimal. I’m suggesting that if it was going to get re-written, I would at least study the basic parameters of the problem by reviewing the workload of the current system.
