Your legacy stack, replaced.
Piece by piece.
Stable systematically replaces brittle legacy systems using an incremental approach, so your team keeps operating while the new system takes over, module by module.
Migration progress

Live parity checks
Six phases,
zero big-bang moments.
Every modernization project follows the same disciplined structure, so the system that goes live is proven before the old one is retired.
Map what you have before we touch anything.
2 weeks with your team documenting every integration, data flow, and dependency. We find the hidden dependencies before they become migration blockers.
The new system wraps the old one.
New modules go live while the old system keeps running. Traffic migrates incrementally until the old system handles nothing and is retired cleanly.
Every record migrated, validated, and verified.
We build custom migration tooling for your data model, run parity checks between old and new systems, and sign off on data fidelity before the old system goes dark.
Cut over one integration at a time.
EDI, APIs, manual feeds: each external integration is rerouted to the new system on its own schedule, tested in shadow mode, then cut over with a rollback plan.
Every phase ships with a way back.
Each migration milestone has a documented rollback path. We don't declare success until the parity checks pass and the rollback has been tested.
Your team runs it from day one.
Code in your repo, infra in your cloud account, architecture docs, runbooks, and a named engineer on-call for 30 days post-launch. No managed services, no lock-in.
From legacy system
to modern platform.
Every migration starts with understanding the real system. Not the documented one. We assess, wrap, migrate incrementally, and retire the old system only when the new one is proven.
We map the whole system before we touch it.
Two weeks of structured discovery: every integration documented, every data model mapped, every dependency surfaced. We deliver a migration blueprint and a risk register before anything is built.
The new system runs in parallel first.
New modules are built alongside the old system. Shadow mode runs both, comparing outputs until the new system matches. No cutover until parity is proven.
Module by module, integration by integration.
We migrate in ordered phases by risk and dependency. Each phase has entry criteria, acceptance tests, and a rollback plan. Your operations don't stop.
The old system goes dark when the new one is proven.
Final cutover only happens when parity checks pass and the team has run on the new system long enough to trust it. We stay on-call through the transition.
Legacy systems replaced,
with receipts.
Metrics are from the completed migration. Not projections. Anonymized where requested.
Replaced a 12-year-old customs filing system in 4 months without stopping filings.
A US customs broker was running entry management on an Access database patched together over a decade. We rebuilt the system module by module (shipment tracking first, then entry processing, then billing), migrating 200K+ records with zero data loss and zero downtime during the 18-week project.
Replaced a spreadsheet-driven ops workflow for a regional freight forwarder.
Operations ran on a combination of Excel, Outlook folders, and a 2009-era TMS that couldn't be integrated with modern carriers. We rebuilt the core ops platform from scratch and migrated the team over six months, retiring all three legacy tools by project end.
Migrating a warehouse management system to a modern event-driven architecture.
An operator of 12 distribution centers was running on a WMS built in 2008 that couldn't communicate with modern ERPs or carrier APIs. We're replacing it incrementally, with the first three facilities live on the new system and the remaining nine in migration.
