.NET Core 2.1 to .NET 9. Angular 7 to 17 and 14 to 21. Zero Regressions. Modernization for Systems That Cannot Go Down.
Lorecs Supply Chain migrated from .NET Core 2.1 to .NET 9 with zero invoice rejections. Kragworks AgTech moved from Angular 7 to Angular 17 across a two-year build that added six modular features. A B2B sales-intelligence SaaS moved from Angular 14 to Angular 21 without disrupting an active Salesforce and HubSpot integration layer. Rorix engineers read the existing system before they touch it, carry over the business logic that never made it into any documentation, and scope migrations against the actual risk surface.
Deliverables
Every engagement is scoped to deliver specific, measurable outcomes.
Codebase Audit
Full assessment of your existing stack: dependencies, security vulnerabilities, performance bottlenecks, and technical debt inventory.
Migration Roadmap
Phased plan to migrate incrementally, module by module, so you stay operational throughout the entire process.
Zero-Downtime Migration
Strangler fig pattern and feature-flag-driven cutover so users never experience an outage during the transition.
Performance Uplift
Typically 3-10x improvement in response times after modernization, with documented before/after benchmarks.
Modern Stack Adoption
Migration to current-generation frameworks, cloud-native services, and containerized deployments.
Test Coverage
We build test suites as we go: unit, integration, and E2E, so every migrated module is regression-proof.
Technologies We Use
Production-proven tools selected for longevity, performance, and ecosystem health.
Why Teams Choose Rorix Technologies
We Have Done This Before
Legacy modernization is a specialization, not a side capability. We have migrated monolithic .NET apps, PHP codebases, and aging Angular 1.x frontends, at production scale.
No Big Bang Rewrites
Big bang rewrites fail. We modernize incrementally with a proven strangler fig approach that keeps your business running.
Risk-Scored Planning
Every module in your system gets a risk score before migration begins. High-risk components are tackled with extra caution and testing coverage.
