Stay ahead of the technology curve and ensure your enterprise platforms are secure, performant, and fully supported. At Associative, we specialize in helping businesses navigate complex infrastructure upgrades, including the critical AEM Java 17 to Java 21 migration.

As an Adobe Bronze Solution Partner, we possess the validated expertise required to handle sensitive upgrades within the Adobe Experience Manager ecosystem.

Why Migrate from Java 17 to Java 21?

Upgrading your AEM backend to Java 21 (LTS) is not just about keeping up with versions; it is about unlocking significant improvements in efficiency and scalability.

  • Performance Gains: Leverage Virtual Threads (Project Loom) for high-throughput concurrency, reducing memory footprint and improving response times for AEM services.

  • Modern Language Features: Utilize Pattern Matching for switch, Record Patterns, and Sequenced Collections to write cleaner, more maintainable backend code.

  • Long-Term Support: Java 21 is a Long-Term Support (LTS) release, ensuring your AEM infrastructure remains compliant with security patches and vendor support lifecycles for years to come.

  • Garbage Collection Improvements: Benefit from the latest Generational ZGC improvements for lower latency operations, crucial for high-traffic AEM sites.

Our Migration Methodology

Migrating an enterprise CMS like AEM requires precision. Our dedicated Java and AEM experts follow a rigorous process to ensure zero downtime and data integrity.

  1. Compatibility Assessment: We analyze your current AEM codebase, custom workflows, and third-party integrations to identify deprecated APIs or libraries incompatible with Java 21.

  2. Code Refactoring: Our team updates your backend logic, leveraging our deep expertise in Java (Spring Boot, Jakarta EE) to ensure full compatibility with the new JDK.

  3. Environment Configuration: We configure your CI/CD pipelines (Jenkins, Docker, Kubernetes) to support the Java 21 runtime.

  4. Rigorous Testing: From unit tests to performance benchmarking, we ensure your AEM instance runs smoother on Java 21 than it did on Java 17.
