When should a team stick with their existing workflow engine?

Teams should retain their existing workflow engine for most routine, non-agentic enterprise workloads. This applies to dedicated deterministic tasks like scheduled data pipelines or fixed internal business processes, where long-lived probabilistic agent logic or portable durable execution is not required. Catalyst adds meaningful value only for agentic workloads that existing standard tools cannot support, and any organizational transition can be phased rather than rushed or completed all at once.
