How Engineering Leaders Use Feature Flags to De-Risk Replatforming and Speed Up Migration

In this session, we explored how engineering leaders are using feature flags and experimentation to reduce risk during replatforming—without slowing teams down.

Our speakers shared practical perspectives on:

• Using feature flags as a control layer to migrate incrementally rather than relying on big-bang releases
• Making clearer go / no-go decisions by measuring impact early and often in production
• Detecting risk sooner through feature-level observability, not just system-level metrics
• Treating feature flags as a lifecycle tool—designed to be rolled out, measured, and retired cleanly
