Legacy upgrade — NZ Rx
Assessment, Rx (refactor & migrate), and incremental modernization for mission-critical legacy systems across New Zealand. Reduce risk, preserve business continuity, and unlock cloud-native value.
- Platform, monolith, or aging integrations
- Risk-aware migration and security hardening
- Phased delivery to protect production
Common challenges we solve
- Slow releases and complex monoliths
- Vendor lock-in and brittle integrations
- Outdated frameworks and unsupported runtimes
- High operational cost and security exposure
Our Rx process focuses on measurable outcomes: faster delivery, lower cost, improved reliability, and predictable security posture.

Our approach — Assess · Rx · Run
1. Rapid assessment
Code health, dependency map, business-critical paths, and migration risks.
2. Rx plan
Strangler patterns, componentization, API contracts, and cutover strategy.
3. Execute & run
Incremental delivery, automated testing, CI/CD, and runbook handover.
Patterns & technologies
We apply proven patterns: strangler, anti-corruption layer, event-driven decoupling, and containerization. Preferred stacks include .NET Core -> .NET 7, Node.js, Go, PostgreSQL, Kubernetes, and managed cloud services.
Case study — Health sector migration (NZ)
We migrated core scheduling services from an on-prem monolith to a containerized microservice suite with zero-downtime cutover and automated failover. Outcome: 65% faster deployments, 40% lower infra cost.
Migration checklist
| Item | Why it matters | Status |
|---|---|---|
| Dependency map | Identify hidden coupling | Required |
| Automated tests | Prevent regressions | Recommended |
| Cutover plan | Safe migration windows | Mandatory |
