AsyncAPI 2.6 to 3.0: Migrating Safely with No-Code Backward Compatibility Checks

AsyncAPI 3.0 introduces many improvements, including support for patterns like request-reply, making it a compelling upgrade. But how can you be sure your migration doesn’t unintentionally alter API behaviour?

In this talk, you’ll learn how to use no-code spec-vs-spec backward compatibility checks to ensure that your upgrade from 2.6 to 3.0 is safe, controlled, and limited to syntax changes alone. We’ll explore how this method catches behavioural mismatches early, enabling teams to adopt AsyncAPI 3.0 confidently—without fear of breaking existing contracts. This talk will involve live demos based on our experience handling migrations in real world projects.
