How do we migrate from Zapier to n8n without breaking anything?
A Zapier to n8n migration playbook: inventory every Zap, map triggers and actions, rebuild in a sensible order, run in parallel, and cut over one workflow at a time.
- Time needed
- 1 to 3 weeks
- Steps
- 5
- Level
- Intermediate
In short: Move from Zapier to n8n in five steps: list every Zap with its trigger, steps, owner and monthly task use; map each trigger and action to an n8n node or an HTTP request; rebuild the simplest, highest-volume Zaps first; run old and new side by side on real data; then switch off each Zap only after its n8n workflow has matched it for a set period. Keep Zapier running for anything you have not proven yet.
When moving to n8n makes sense
| Reason | Why n8n helps |
|---|---|
| Task volume is driving cost | Self-hosted n8n has no per-task charge; you pay for hosting and upkeep instead |
| Workflows need loops, branching or code | n8n has Code nodes, sub-workflows and fine control over items |
| Data must stay in your infrastructure | n8n can be self-hosted |
| You need custom APIs | The HTTP Request node covers apps without a built-in node |
Stay on Zapier if your Zaps are few, simple and cheap, or nobody on the team can own a self-hosted service.
Step 1: Inventory every Zap
Export or list each Zap and record:
| Field | Why |
|---|---|
| Name and owner | Someone must sign off the new version |
| Trigger app and event | Determines the n8n trigger node or webhook |
| Steps and filters | Every step needs an equivalent |
| Monthly tasks | Prioritises the migration |
| Connected accounts | Credentials must be recreated in n8n |
| What breaks if it stops | Sets testing depth |
Turn off and delete Zaps nobody owns or needs before migrating anything.
Step 2: Map triggers and actions
- For each app, check whether n8n has a built-in node with the same trigger and actions.
- Where it does not, use a webhook trigger or the HTTP Request node with the app's API.
- Note differences: polling intervals, field names, how lists of items are handled, and how errors surface.
- Replace Zapier-only tools (Formatter, Paths, Filters, Storage) with n8n nodes such as Set, IF, Switch, Code and a database or data table.
Step 3: Rebuild in a sensible order
Start with Zaps that are high volume but simple, because they save the most and are easiest to prove. Leave complex, business-critical Zaps until the team is comfortable with n8n. Build each workflow with an error workflow that alerts a named person.
Step 4: Run in parallel
Run the n8n workflow alongside the Zap, writing to a test destination or a log rather than the real system where possible. Compare outputs for every run over an agreed period. Where both must write to the real system, use an idempotency key so the second write does nothing.
Step 5: Cut over one workflow at a time
- Pause the Zap.
- Activate the n8n workflow on the real destination.
- Watch the first runs and the error alerts.
- Keep the Zap paused, not deleted, until the next billing cycle in case you need to roll back.
Hosting and reliability
If you self-host, plan for backups, updates, monitoring and a runbook. Our n8n task runner reliability playbook covers what to do when executions stop. Also watch for expired credentials, a common reason workflows quietly stop (why your automation keeps disabling).
FAQ
Can Zaps be imported into n8n automatically?
There is no reliable one-click import. Treat it as a rebuild using the Zap as the specification.
How long does a Zapier to n8n migration take?
It depends on the number and complexity of Zaps. Inventory first, then estimate per workflow.
Is self-hosted n8n always cheaper?
Not always. You save task fees but take on hosting and maintenance. Compare against your real task volumes and team time.
Should we run both platforms long term?
It is fine to keep a few simple Zaps on Zapier if they are cheap and stable. Move what gives the most benefit.
How Octacer helps
Octacer migrates and maintains automations on n8n, Zapier and Make. We inventory, rebuild, run in parallel and hand over documented workflows. See our automation services.
