Can I migrate existing Restate services to Diagrid Catalyst without rewriting my code?

Migration from Restate to Catalyst may require significant rework because they use different execution models. Restate relies on journaled services and virtual objects, while Catalyst uses Dapr Workflows and agent runners. If your Restate services are deterministic, you can port them to Catalyst's workflow activities, but agent-specific logic would need adaptation to Catalyst's framework-agnostic runner model. Evaluate your code's coupling to Restate's runtime before migrating.
