Java modernization services in Hong Kong

A senior team a short time-zone hop away, building products ready to scale across the region.

Clarigo Infotech upgrades and modernizes Java applications: Java 8 or 11 to Java 17 or 21, older Spring and Spring Boot versions to current releases, javax to jakarta namespaces, and heavy application servers to lightweight containers. Where it helps, we split monoliths into services. Every step is covered by automated tests, so the application keeps working while it is upgraded.

Hong Kong companies most often hire us for fintech, trading and logistics platforms, and AI.

What we do

What our Java modernization covers

Java version upgrades

Java 8 or 11 to Java 17 or 21 LTS, including library and build-tool updates.

Spring Boot upgrades

Spring Framework and Spring Boot 1.x and 2.x to current versions, including the javax to jakarta move.

App server to containers

WebLogic, WebSphere, JBoss or Tomcat deployments moved to Docker, Kubernetes or managed cloud services.

Monolith to microservices

Carefully split large Java applications into services, only where it improves delivery or scale.

Build and CI/CD

Maven and Gradle cleanup, automated tests and pipelines that make every release safe.

Performance and security

Dependency and vulnerability fixes, JVM tuning and profiling for faster, safer applications.

In depth

How we approach Java modernization

Why move to Java 17 or 21

Newer long-term-support versions bring better performance, security updates and language features, and current Spring Boot versions require them. Staying on Java 8 means growing security and hiring risk.

Upgrade path, not a rewrite

We upgrade in stages (build tools, dependencies, language version, framework), testing at each stage, so you always have a working, releasable application.

Process

How it works

1. Free assessment

We review your code, dependencies, infrastructure and data, then give you a written migration plan, risks and a fixed quote.

2. Plan and safety net

We add automated tests and monitoring around what exists today, so every change can be checked against the old behaviour.

3. Migrate in small steps

Module by module, with both versions running side by side where needed. You see progress in a demo every week.

4. Cut over and support

A planned switch-over with a rollback path, then the same engineers stay on to fix, tune and keep it current.
