When should I stick with my current workflow engine instead of Catalyst?

You should stick with your current workflow engine if its core use cases align with your team’s existing priorities. Most general tools excel at their original design goals, like scheduled data pipelines, BPM, or CI/CD orchestration, which may not require agentic durable execution. Durable execution differs from exact-once delivery, so clarify your needs first. Avoid migrating without clear high-impact use cases.
