Version Upgrades & Language Migration for Future-Proof Codebases
We modernize aging codebases with structured migration paths — from .NET Framework 4.x to .NET 6/8, VB.NET to C#, PHP to Laravel, Java to .NET, and AngularJS to Angular or React. Breaking changes remediated, dependencies updated, and parallel-run strategies that keep production stable.

Modernize Your Stack Without Rewriting From Scratch
Technology debt accumulates silently until security patches stop, hiring becomes impossible, and every feature takes twice as long. Our migration engineers assess your codebase, map breaking changes, and execute phased upgrades that preserve business logic while unlocking modern runtime performance and cloud deployment options.
Whether you need a WinForms application moved to .NET 8, a VB.NET module converted to idiomatic C#, or a PHP monolith re-platformed to Laravel, we apply proven parallel-run strategies, automated test suites, and dependency modernization to de-risk every transition.
What We Build
-
.NET Framework to .NET 8
WinForms, WPF, ASP.NET, and class library upgrades with nullable reference types, async patterns, and cross-platform readiness.
-
Language Conversions
VB.NET to C#, Java to .NET, and PHP to Laravel with behavioral equivalence testing and incremental module replacement.
-
Frontend Framework Migration
AngularJS to Angular or React with component mapping, routing modernization, and API contract preservation.
Key Migration Capabilities
End-to-end expertise tailored to your data and platform requirements.
Codebase Assessment
Automated static analysis, dependency audit, breaking change inventory, and effort estimation with prioritized migration waves.
Dependency Modernization
NuGet, npm, and Composer package upgrades with security vulnerability remediation and license compliance review.
Breaking Change Remediation
API signature updates, deprecated API replacements, configuration migration, and compiler warning resolution.
Parallel Run Strategy
Side-by-side environments, shadow traffic, output comparison, and gradual cutover with instant rollback capability.
Automated Test Harness
Unit, integration, and snapshot tests that validate behavioral parity between legacy and migrated code paths.
Documentation & Handoff
Migration playbooks, architecture decision records, and team training for ongoing maintenance on the new stack.
Our Migration Technology Stack
Battle-tested tools and platforms for reliable data operations.
Our 4-Step Upgrade Process
A structured workflow that delivers predictable, high-quality outcomes.
Audit & Roadmap
Inventory all projects, dependencies, and integration points. Produce a phased migration plan with risk scores and timelines.
Pilot Module
Migrate a low-risk module first to validate tooling, test coverage, and deployment pipelines before touching critical paths.
Phased Migration
Execute wave-by-wave conversions with regression gates, stakeholder sign-off, and parallel production validation at each milestone.
Cutover & Optimize
Final switchover, legacy decommission, performance tuning, and knowledge transfer to your internal development team.
