Migrate Customer.io From Zapier to n8n
Step-by-step migration of Customer.io zaps to n8n workflows — parity checklist and rollback plan.
Key takeaways
- Inventory before you touch a thing.
- Shadow-run for a week.
- Cutover, then keep old paused as rollback.
- Consolidate multi-zap chains.
Migrating Customer.io zaps to n8n is straightforward if you follow the parity checklist and roll out in shadow mode first. Here's the exact playbook.
Inventory
List every Customer.io zap: trigger, actions, filters, and task volume. Rank by criticality.
Rebuild in shadow
Rebuild in n8n with production credentials but writes disabled. Compare outputs to Zapier for a week.
Cutover
Enable writes in n8n; disable in Zapier the same minute. Keep the old zap paused for 14 days as a rollback.
Learn and shrink
Once green, refactor multi-zap chains into a single n8n workflow. You'll cut cost and clarity in one move.
Frequently asked questions
- How long does it take?
- A few hours per non-trivial zap. Sync-only zaps are 20 minutes.
- Any tools to help?
- Not automatic — but the mapping is 1:1.
- Downtime?
- None if you shadow-run first.
- Rollback?
- Un-pause the old zap. That's why you keep it 14 days.
