This post details a practical, incremental migration strategy for moving over 100 workflows from Inngest to Temporal. It outlines a four-step process (Characterize, Scaffold, Cut over, Remove) using feature flags and shared business logic to ensure safety and reversibility. It provides a detailed mapping of Inngest concepts (cron triggers, concurrency, retries, step.run) to their Temporal equivalents (Schedule, Workflow, Activity, Schedule overlap, Activity retry policies), highlighting critical differences in retry counting and the need to move non-deterministic code into Activities during migration. A specific example of migrating a scheduled drift check workflow is provided.
