What changes
From November 17, 2026, Next Gen Zaps will fail at remaining Code by Zapier steps. Rebuild the step, or disable the Next Gen Zap and turn the original Classic Zap back on. This is a documented deadline, not a new product launch.
Who should check
The immediate audience is businesses already migrating operational workflows to Next Gen Zaps. Classic Zaps continue unchanged; migration is optional. Next Gen Zaps remain request-only early access on Professional, Team and Enterprise. Availability.
For an owner, the takeaway is to ask whoever manages automation to inspect the migrated workflows specifically. Using Zapier does not mean every business process is affected.
A practical checklist
- List migrated workflows with their owner, business purpose, inputs, expected result and manual fallback.
- Inspect dependencies after each code step. Importing replaces Code by Zapier with a placeholder that provides no output to later steps. Import limitations.
- Compare expected and actual results from rebuilt logic using controlled records. Include an empty field, a duplicate record and an unusual data format. This is editorial advice, not a claim that Zapier automatically performs those checks.
- Approve the test separately. Test uses live connections rather than an isolated sandbox. Choose a safe recipient and controlled data; assess whether testing will send a message or change a record. Workflow Manager.
- Prepare a fallback to the original and name the person responsible for switching. Two active copies can perform the same job twice. Migration guidance.
Why it matters to a small business
An illustrative example: if code prepares order data for the next step, check the final record’s accuracy rather than only whether a run completed. This is not a documented incident or the result of our own product testing.
The useful outcome is a clear list of what has been repaired, what stays on Classic and who monitors initial runs. Do not leave that work until the deadline, and do not interpret migration as a requirement to upgrade every automation.
