LEGACY SYSTEMS & MODERNIZATION
Don’t rebuild everything,
just what makes sense
We modernize legacy systems without breaking what still works. From VB6 and Classic ASP to scalable .NET platforms, we deliver smooth, phased upgrades that keep your operations running and ready for what’s next.

NOT EVERYTHING HAS TO BE REBUILT

We focus on architecture, not overhauls—identifying what to migrate, what to retain, and how to evolve your system without disrupting what works.
Legacy systems often power critical functions, so we start by understanding what still delivers value, not by assuming everything is outdated.

Strategic analysis before any changes
Strategic analysis
before any changes
We audit your legacy stack, not just the codebase, but how your system is used in practice. That gives us insight into business-critical functions and user flows that shouldn’t be disrupted.

Controlled transformation, not big bang rewrites
Instead of ripping everything out, we break the modernization into clear phases — allowing your team to operate normally while upgrades happen in parallel.

If parts of your system are stable, fast, and cost-efficient, we help you keep them. Our goal is to modernize around the strengths, not blindly erase them.

Legacy doesn’t scare us. We’ve worked with systems built decades ago and brought them into today’s stack.
VB6 to .NET Core migration
We migrate core VB6 applications to modern .NET platforms, safely, efficiently, and without losing business logic.
WebForms to modern frontend (React, Blazor)
We replace outdated interfaces with responsive, user-friendly frontends using technologies like React or Blazor.
Microsoft Access to SQL Server
We transition your Access-based systems to SQL Server for better performance, security, and scalability
Classic ASP to REST API architectures
We re-engineer Classic ASP logic into clean, scalable RESTful APIs that integrate easily with modern applications.
UI/UX redesign for legacy UIs
We give your legacy interface a complete design overhaul, improving usability without disrupting how your team works.
Backend logic extraction
& modularization
We isolate and refactor backend logic into clean, modular services that are easier to maintain and scale.
Integrating legacy systems
with cloud services
We connect your existing systems with modern cloud platforms — unlocking automation, reporting, and new capabilities.
Structure, stability, and zero downtime, built into every step
Legacy upgrades don’t have to be risky. Our process ensures systems stay online while transformation happens.
1.
Codebase and dependency audit
We begin by analyzing your current system’s code and all third-party dependencies. This helps us identify technical debt and compatibility issues early.
2.
Risk mapping and priority analysis
We map out all potential risks and prioritize components based on business impact, helping guide a safe and logical modernization sequence.
3.
Architecture design and
stack planning
A modern architecture is proposed that balances scalability, performance, and maintainability—tailored to your business and technical needs.
4.
Incremental migration strategy
We break down the migration into manageable steps, allowing parts of the legacy system to continue running while new components are implemented.
5.
Parallel testing and validation
New and old systems run in parallel with mirrored data, allowing for safe testing, bug detection, and user acceptance without risking operations.
6.
Go-live planning and transition
A go-live plan ensures a seamless switch with minimal disruption—backed by rollout procedures, rollback contingencies, and internal training.
7.
Post-deployment support
and monitoring
After launch, we remain involved—monitoring performance, fixing post-launch issues, and offering ongoing support for continued stability.
