Your Automation Platform Is Shutting Down: Migrate One Workflow to n8n Without Rebuilding the Wrong Behavior
Short summary
A practical guide for migrating automation workflows from a retiring platform to n8n without preserving silent failures. The approach starts with one representative workflow and a written acceptance contract covering triggers, field lineage, transformations, state, irreversible actions, and terminal results. It emphasizes testing invalid inputs, missing data, and wrong-source events rather than just verifying the happy path.
- •Start with one canary workflow and a written acceptance contract, not a full fleet migration
- •Document triggers, field lineage, transformations, state, and irreversible actions before building
- •Test invalid, missing, and wrong-source inputs — a successful happy path is necessary but not sufficient
