Java-based legacy application migration

Transform legacy Java applications with a secure, high-performance architecture built for today’s demands
Let’s talk Java migration

Migrating Legacy Java Frameworks

Legacy Java frameworks weren’t built for
today’s digital demands.

Older Java applications like those built with Struts, JSF, Swing, or EJB were once reliable. But they no longer support the
speed, flexibility, and user experience that modern business demands.

Limited scalability

Legacy frameworks depend on server-side rendering, which hinders performance in dynamic, high-traffic environments.

Dated user experience

Technologies like Swing and JSF fall short when it comes to responsive, interactive interfaces—especially for mobile or web users.

Complex, heavyweight architecture

Older stacks require complex configuration, rely on traditional app servers, and aren’t optimized for cloud-native deployment.

Harder to maintain and scale

Monolithic, tightly coupled systems make updates difficult and slow down development cycles.

The benefits of migrating to Spring
Boot with Angular or React

Modernizing to Spring Boot with a dynamic web UI (like Angular or React) transforms your application and business

Lightweight, modular architecture

Spring Boot simplifies backend development and supports scalable APIs and microservices.

Dynamic, modern frontends

Angular or React enables interactive single-page apps with real-time responsiveness and improved usability.

Cloud-native readiness

Built-in compatibility with containerization and cloud platforms speeds up deployment and innovation.

Faster, decoupled development

Clear separation of frontend and backend allows teams to work independently and ship faster.

Long-term adaptability

A modern stack ensures easier updates, better maintainability, and alignment with today’s agile and DevOps workflows.

Our proven 5-step methodology

Migrating from a legacy Java framework isn’t just a technical upgrade, but a chance to re‑architect your applications for speed, scalability, and modern user experiences. We make the process straightforward and predictable, so you get all the benefits without the headaches.

1. Scope

We work with you to assess your existing Java application, whether it’s built on JSP/Servlet, Struts, JSF, EJB, or Swing. Together, we define the performance, scalability, and usability goals for your migration.

2. Plan

We design a migration roadmap that outlines your new backend (Spring Boot) and frontend (Angular or React), maps out dependencies, and incorporates any needed API, microservice, or cloud integrations.

3. Migrate

Using a mix of industry‑leading tools and our proprietary Spring‑Boot Migrator, we convert your backend logic, rebuild or modernize the UI, and restructure your application for a scalable, cloud‑ready environment.

4. Test

Our team runs thorough QA, regression, and performance tests to ensure your new system matches or exceeds the functionality of your legacy application—while improving speed, reliability, and user experience.

5. Deploy

We roll out the new application with minimal downtime, provide user training if needed, and offer ongoing support so your upgraded platform keeps delivering long‑term value.
