Proven before cutover
System & data migration
Get off an old system without betting the company on a big-bang rewrite. We build the new system alongside the live one, move your data with an idempotent, re-runnable tool — never a one-shot script — and prove old and new match against a copy of your real data before anyone cuts over.

What's included
- Migration scoped module-by-module — the legacy system stays live throughout
- An idempotent, re-runnable migration tool with dry runs that roll back
- A parity harness comparing old and new, field by field, on a copy of your real data
- Cutover with verified backups and a rollback plan — only once parity is proven
Who it's for
Teams stuck on an aging platform — a legacy framework, a desktop ERP, an unsupported stack — where a rewrite has already failed once or feels too risky to attempt. We run our own products through exactly this process.
How it works
Every engagement runs the same loop: you brief the problem, we scope it into a fixed deliverable, AI agents build in parallel, a senior engineer reviews and owns every line, and it ships to production gated by automated tests. See how we work →
