Legacy App Modernization for Aging, Undocumented, and Business-Critical Systems

We modernize fragile stacks like VB6, EJB, and ASP.NET using Legacyleap—our GenAI platform that automates analysis, refactoring, and replatforming. Faster than traditional SIs, with traceability, functional parity, and rollout confidence baked into every line of code.

We rearchitected an EJB monolith into revenue-generating microservices for ULabs, using blue-green deployment with zero downtime. For a global health tech firm, we accelerated VB6 modernization with Legacyleap-automating 60% of the lift and reducing roadmap timelines from years to weeks, with test coverage and traceability built in.

FAQs About Legacy App Modernization

What legacy technologies do you support for modernization?

We modernize VB6, ASP.NET, AngularJS, EJB, Classic Java, and other aging frameworks — even when documentation is missing.

Can you modernize apps with no documentation or original developers?

Yes. Legacyleap uses GenAI to analyze codebases, extract workflows, and surface dependencies — even in black-box environments.

How do you ensure functional parity in the modernized system?

We generate acceptance tests and regression harnesses to validate parity at every step — with rollback-ready deployments if needed.

Do you support phased modernization or full rebuilds?

We offer both. We help you assess feasibility and ROI — and design programs that mix refactoring, rebuilds, and sunsetting, based on app criticality.

How long does it take to modernize a legacy app?

Timelines vary, but we've condensed multi-year roadmaps into 6-week sprints using Legacyleap, blue-green deployments, and GenAI acceleration.

What modern stacks do you replatform to?

.NET Core, Spring Boot, React, Next.js, and containerized deployments on AWS, Azure, or GCP — aligned to your enterprise infra.
