Butterfly Data's principal IT consultant, Henry Newman-Burke, and data scientist, Maja Strawinska will be presenting at the Public Sector Connect Data and AI Summit 2026, sharing expert insight on governing data migration across large-scale public sector programmes.

No surprises on moving day: Governing data migration at scale

In their session, “No surprises on moving day: Governing data migration at scale,” Henry and Maja use the familiar analogy of moving house to explore how organisations can successfully manage complex data migrations - particularly when upgrading to smarter, AI-enabled platforms.

Just like a house move, successful migration requires:

  • Clear planning and decision-making
  • Knowing what data to keep and what to retire
  • Accurate labelling through strong metadata and classification
  • Solid foundations for future AI capabilities
  • Robust governance to prevent disruption

For public sector organisations modernising legacy systems, the risks of poor migration are significant, from compliance issues to service disruption. Strong governance ensures data is not only moved safely, but structured and prepared to power the next generation of digital services.

Supporting AI-ready public services

Together, Henry and Maja will highlight how governance-led data migration reduces risk, protects compliance and enables trustworthy AI adoption across government.

The Public Sector Connect Data and AI Summit 2026 brings together leaders shaping the future of public services. Butterfly Data’s session will provide practical insight for those planning cloud transitions, system upgrades or AI implementation to ensure there are truly no surprises on moving day.
