Modernize Without Losing What Works.
Two decades of pre-AI enterprise experience — applied with AI-era tooling.
Most firms treating legacy modernization like a greenfield rewrite destroy the institutional knowledge embedded in your existing system. We don't. Our engineers have spent 20+ years working with pre-AI enterprise stacks — COBOL, Oracle, monolithic Java, .NET, AS/400 — and we migrate them incrementally, preserving business logic while removing the burden of unmaintainable infrastructure.
Legacy Stack Assessment
Deep analysis of your current system: architecture, data model, integrations, and undocumented business rules.
Incremental Migration Strategy
We migrate in slices, not big bangs — keeping your business running throughout.
Zero Knowledge Loss
Every business rule, edge case, and workflow is documented and preserved before migration begins.
Parallel Running Validation
New and legacy systems run side-by-side with automated output comparison until confidence is established.
Stakeholder Alignment
We run workshops with business owners to surface undocumented requirements hiding in spreadsheets and people's heads.
Modern Stack Delivery
Target stacks using current, maintainable technology: cloud-native, containerized, API-first.
Discovery & Documentation
We interview stakeholders, analyze the existing system, and produce a complete inventory of business logic.
Migration Architecture
Design the target state and the incremental migration path. Define the strangler-fig boundaries.
Slice-by-Slice Migration
Migrate one functional slice at a time, running old and new in parallel to validate equivalence.
Validation & Cutover
Automated output comparison, stakeholder sign-off, and controlled cutover with instant rollback capability.
Decommission & Documentation
Safely decommission the legacy system and hand over complete documentation of the new architecture.
