The Secret to Safe Modernization: Behavior-Driven Migration

Modernizing a legacy system doesn’t fail because of bad code , it fails because it breaks customer behavior. In this video, I explain how ATDD and BDD can be used as a migration strategy, not just a testing technique. You’ll see how to safely replace a legacy platform, preserve critical workflows, and move customers to a new modern web app without breaking trust or causing regressions. What you’ll learn: Why most legacy rewrites fail How to turn legacy behavior into executable contracts The step-by-step ATDD/BDD migration framework How to validate behavior parity between old and new systems How to roll out safely using dual-run and feature flags This approach has been used to modernize mission-critical platforms where downtime, data mismatches, and user friction are not acceptable. If you’re leading a rewrite, modernization, or platform migration, this is the strategy you’ve been missing.
