Outcome
A clean move to the new tool with history intact and a verified record count, instead of a risky one-shot import that loses or scrambles data.
High Automation system
Tool Migration Workflow
A staged migration that moves contacts, history, and automations from a legacy tool to a new one through field mapping, a dry-run validation, a reversible batch import, and a reconciliation check before cutover.

System facts
Tool Migration Workflow uses an event-driven automation layer for AI Automation. A staged migration that moves contacts, history, and automations from a legacy tool to a new one through field mapping, a dry-run validation, a rev... The architecture connects inventory the source data, make, n8n, and completed workflow with an explicit control path.
Main risk
A one-shot migration silently drops fields, merges the wrong records, or loses history, and there is no way to undo it.
Prevention
Always dry-run on a sample first, keep export backups, import in reversible batches, and reconcile counts before trusting the result.
Fallback
Quarantine records that fail validation and keep the legacy system read-only and live until reconciliation passes.

How it is built
A staged migration that moves contacts, history, and automations from a legacy tool to a new one through field mapping, a dry-run validation, a reversible batch import, and a reconciliation check before cutover.
- 01Inventory the source data and map every field, tag, and pipeline stage to the destination schema
- 02Run a dry-run import on a sample batch, exporting a validation report of matches, conflicts, and dropped fields
- 03Execute the full import in reversible batches with backups, deduping against any existing destination records
- 04Reconcile source vs destination counts and key fields, then cut over triggers once parity is confirmed

- CSV/API exports
- Event layer: Inventory the source data and map every field, tag, and pipeline stage to the destination schema
- Validation layer: Run a dry-run import on a sample batch, exporting a validation report of matches, conflicts, and dropped fields
- Branching layer: Make carries Tool Migration Workflow through validated triggers, branches, writebacks, and exception paths.
- Writeback layer: n8n handles routine steps while always dry-run on a sample first, keep export backups, import in reversible batches, and reconcile counts before trusting the result.
- Exception layer: A clean move to the new tool with history intact and a verified record count, instead of a risky one-shot import that loses or scrambles data.
