Many profitable enterprise applications still run on end-of-life Python 2.7, early Python 3.6/3.7, legacy Django 1.x/2.x/3.x, or Google App Engine First-Generation runtimes. Upgrading these codebases without breaking production traffic or halting feature delivery requires disciplined static analysis, automated test harnesses, and incremental Strangler-Fig routing.
