As European public sector organizations pursue digital sovereignty, the technical migration from proprietary to open source solutions is only half the battle. Technology is often the easy part. The real challenge lies in transforming not just infrastructure, but mindsets, workflows, and institutional culture. True independence requires successfully leading organizational change - preparing teams, managing resistance, and building confidence in open source alternatives.

This talk shares proven change management strategies from leading IT transformations and guiding public sector clients through transitions from Jira to OpenProject, demonstrating how to build sustainable and resilient digital ecosystems that serve citizens rather than vendors. You'll learn how to:

• Co-create change through proven leadership best practices
• Create ownership for the open source solutions within public sector
• Build the business case and frame the open source narrative that resonates with public sector stakeholders and decision-makers
• Drive the mindset shift to FOSS
• Identify your use cases and foster transition to open source products
• Build internal champions who drive adoption across departments

Drawing from real-world public sector experiences and Rosanna Sibora's experience in driving IT transformations, this session reveals the human factors that make or break digital sovereignty initiatives. Whether you're planning your first migration or looking to improve your change management approach, you'll leave with actionable frameworks for leading successful transitions to independent and interoperable digital workspaces.
