Source-to-target map
Trigger, inputs, transformations, state, irreversible actions, outputs, and substitutions documented before the rebuild.
ONE REPRESENTATIVE WORKFLOW · 72 HOURS · SHARED 3-SLOT CAP
Move the workflow.
Preserve the outcome.
When an automation tool closes or a legacy flow becomes unmaintainable, a node-for-node copy is not enough. Builderlog migrates one representative workflow into n8n with an explicit field map, five anonymous acceptance cases, evidence, and a recovery runbook.

The pilot shares the existing three-slot one-workflow inventory. No passwords, production login, or live customer records are collected.
- 1 workflow
- 2 external services max
- 5 acceptance cases
- 0 credentials collected
THE MIGRATION TRAP
Equivalent nodes can still produce a different business result.
Trigger semantics: does the replacement start on the same event and replay boundary?
Field lineage: does each value still come from the intended source record?
Side effects: can a timeout after a committed write create a duplicate on retry?
Terminal evidence: can an empty branch silently skip the required outcome?
DELIVERABLES
A migration contract you can inspect.
Importable n8n workflow
One workflow built around the confirmed outcome, using placeholders where credentials connect in your own environment.
Five acceptance cases
Valid, invalid, missing, duplicate or retry, and wrong-source cases with observable expected results.
Evidence + runbook
Acceptance receipt, artifact hashes, setup notes, recovery actions, and the boundary for any follow-on migration.
GOOD PILOT
Prove one representative path first.
Best for one workflow whose source behavior, sample input, and required outcome can be described without production access.
NOT INCLUDED
No fleet-wide promise hidden inside $299.
Dozens of client copies, live data migration, account administration, undocumented multi-workflow systems, and ongoing support require a separate written scope after the pilot.
3–4 WORKFLOWS × MANY CLIENTS
Do not rebuild every copy first.
If one workflow is repeated across many client environments, the first deliverable should be a tenant-neutral contract—not dozens of edited copies. Separate shared workflow logic from validated client configuration, prove one synthetic tenant boundary, and deploy to one canary before any fleet rollout.
The $299 pilot covers one representative workflow. The $799 multi-client contract mode covers one process and up to three connected workflow files, a tenant-neutral configuration schema, one synthetic canary, and a rollout/rollback manifest. Neither includes bulk production deployment, live client records, client credentials, or ongoing fleet management.
- 01 · Shared templateVersion reusable logic once instead of editing every client copy.
- 02 · Client configurationValidate required fields and reject unknown or incomplete tenant settings.
- 03 · Tenant boundaryProve one client's configuration cannot read or update another client's records.
- 04 · Canary + rollbackExpand only after one synthetic tenant passes and the previous version can be restored.
EVIDENCE BEFORE PAYMENT
Inspect the delivery shape—not a fabricated case study.
The public Builderlog reference packet contains three workflow JSON files, anonymous fixtures, an acceptance receipt, a recovery runbook, and a portable verifier. All three JSON files were accepted by the n8n 2.31.0 CLI importer on Node 22; the packet verifier passes 41 structural checks and 11 workflow or topology cases.
This proves importer acceptance and packet integrity only. It is Builderlog-owned reference work—not buyer-specific production execution or a customer result.

Before purchasing
What fits the pilot?
One existing workflow with one primary outcome and up to two external services. The source can be another automation platform, a documented manual process, or a legacy n8n workflow.
Do you migrate live customer data?
No. Builderlog works from a sanitized export, field map, and synthetic examples. Credentials and production records stay in your environment.
How do you prove the n8n version matches?
The handoff includes a source-to-target map, five anonymous acceptance cases, observable result evidence, artifact hashes, and a recovery runbook.
Can this cover several workflows or many client copies?
The $299 pilot covers one representative workflow. The separate $799 multi-client contract mode covers one process and up to three connected workflow files, plus a tenant-neutral configuration schema, one synthetic canary, and a rollout/rollback manifest. Neither option includes production deployment across every client account.
When does the 72-hour window start?
After the workflow boundary, sanitized source material, and expected result are complete and confirmed.
