How do I manage in-flight work during Catalyst migration?

Prioritize resolving in-flight work before full cutover to avoid conflicting state between platforms. Route new work to Catalyst incrementally, and flag existing in-flight tasks to finish on the original engine or migrate their state safely. Use observability tools to track both workload streams without mixing execution contexts. Note that observability data alone is not a full audit record, so cross-check state consistency for critical tasks.
