Services/02

Get off the system everyone is afraid to touch.

Legacy migrations fail when teams try to rewrite everything at once and discover the old system encoded twenty years of business rules nobody documented. We run migrations as a controlled engineering discipline: parallel-run validation, reconciliation reports, staged cutovers, and a rollback path at every step. The playbook is the same whether the legacy estate is an aging warehouse, a proprietary ETL suite, a homegrown application, or the spreadsheet empire that grew up around all three — and our founders have run it at Vivint, Ancestry, and across consulting clients.

Signals

You probably need this if…

  • 01Critical workflows run on aging databases, hand-scheduled jobs, or desktop tools nobody fully understands — SQL Server, Oracle, DB2, Access, we've seen them all
  • 02The vendor for a critical system is end-of-life, raising prices, or both
  • 03You're locked into a proprietary ETL, BI, or ERP platform and every renewal feels like a hostage negotiation
  • 04A homegrown application still runs the business, and the person who built it is gone
  • 05Compliance or security teams have flagged the platform you can't move off
  • 06Your roadmap is blocked because every change to the old system is too risky
  • 07A previous migration attempt stalled and made things worse

What we build

Deliverables, not decks.

01

System archaeology

We reverse-engineer the undocumented business logic — stored procedures, scheduled jobs, spreadsheet glue — and produce a verified map of what actually runs your business.

02

Migration architecture

Strangler-fig decomposition, dual-write or CDC-based sync, and a phased plan where each stage delivers value and none bets the company. Warehouse-to-cloud, on-prem-to-SaaS, monolith-to-services, or vendor-to-owned — the shape adapts to the estate.

03

Parallel-run reconciliation

Old and new systems run side by side with automated comparison reports until the numbers match to the penny. Cutover happens when the evidence says so, not the calendar.

04

Zero-downtime cutover

Rehearsed, scripted, reversible. Your users notice the new system is faster — and nothing else.
