The database management system market has long been dominated by proprietary solutions, increasingly associated with rising costs, vendor lock-in, and strategic dependency. With PostgreSQL, a mature open-source alternative exists that is not only functionally competitive but often technically superior. In the context of digital sovereignty, PostgreSQL is becoming a strategic necessity rather than just a technical choice.

This talk presents a practical, experience-driven approach to migrating from proprietary systems to PostgreSQL, covering the entire lifecycle from architectural planning to operations and long-term support.

We explore real-world scenarios ranging from simple lift-and-shift to complex transformations, while discussing typical risks, decision frameworks, and common pitfalls. Finally, we examine how organizations can achieve true digital independence and cost reduction through open-source adoption, delivering a clear blueprint for success.
