That's a valid point, but the scale makes it far from trivial. We are talking about the energy sector here, it's high-stakes and high-load. The current backend isn't just a simple SQL instance; a standard MySQL/Postgres setup would likely choke under the sheer volume of real-time sensor data coming in every few seconds.

Rewriting the client isn't just a matter of "money", it's about finding specialized engineers who understand these specific industrial protocols and high-throughput architectures. In our field, "intermediate solutions" can take years to certify and deploy. That’s why we’re forced to maintain this legacy IE/ActiveX stack in a secure way while we evaluate long-term infrastructure overhauls.
