How can I run old and new engines side by side during migration?

Parallel dual-engine deployments offer a safe way to validate Catalyst during migration without disrupting live production workloads. Route a small subset of traffic to Catalyst while keeping most work on your existing production engine, log all outputs for systematic result comparison, and use regular shared monitoring to track performance across both systems. Note that observability is not an audit record, so you may need to perform manual cross-checks as needed.
