Case Study
If the core is the problem, why not upgrade the foundation?
Migrating from an aging MySQL 5.7 instance to a modern PostgreSQL database is the logical enterprise choice. It handles complex data structures far better.
But running the simulation reveals a fatal flaw: the 10-year-old Java API is deeply entangled with MySQL-specific syntax, triggers, and procedures. Swapping the database necessitates a complete, immediate rewrite of the entire backend just to keep the lights on. It’s too massive a leap for step one. Rejected.
This path doesn't work. Time to reconsider.
