Legacy systems are a reality. But they don't have to be a destiny. This talk explores how we actively manage technical debt through quality improvement (SonarQube, AI-refactoring, test coverage). We'll present battle-tested strategies for migrations and building scalable architectures. A special emphasis will be placed on the role of Enabling Teams and Platform Engineering, which pave the way for efficient transformations. Discover how to make your software systems future-ready and sustainable—and empower your teams to be the "Lifecycle Heroes" who bring this vision to life.
