Assessment of Current Environment
A successful OpenJDK migration starts with understanding your current environment. We work with you to evaluate your Java deployments, applications, dependencies, infrastructure, and operational requirements to identify potential issues before migration begins.
This phase varies depending on your infrastructure, but usually includes reviewing Oracle Java usage, build pipelines, monitoring tools, integrations, and application dependencies. We also identify compatibility risks that could affect functionality, performance, or security after migration.
For upgrades that involve moving from Java EE to Jakarta EE, we identify code, libraries, frameworks, and application servers that still rely on affected javax.* packages and must move to jakarta.*. We also determine whether technologies such as Tomcat, Jetty, WildFly, or Spring must be upgraded to versions that support the Jakarta EE namespace.
By taking a complete inventory of your environment, we’ll establish a strong starting point and reduce the likelihood of unexpected issues later in the project.
Planning and Scoping
Once the assessment is complete, OpenLogic builds a migration plan that aligns with your technical and business goals.
We define project scope, migration timelines, testing requirements, deployment strategies, rollback procedures, and success criteria. Our architects also help prioritize workloads, identify dependencies, and develop an approach that minimizes disruption to users and business operations.
When Jakarta EE namespace changes requires affected javax.* references to move to jakarta.*, the plan accounts for updates across application code, application servers, frameworks, libraries, build processes, and deployment configurations. By coordinating our approach, incompatible Java EE and Jakarta EE components are prevented from creating additional work during implementation.
The result is a practical roadmap that breaks down project goals, timelines, responsibilities, and expected outcomes.
OpenJDK Migration Execution and Validation
With a plan in place, OpenLogic executes your OpenJDK migration. Our architects work alongside your team to deploy new environments, validate configurations, and address any compatibility issues that arise. We can also help update affected javax.* imports and configuration references to jakarta.*, upgrade related frameworks and application servers, and resolve compatibility issues across the Java application stack.
This includes installing and configuring OpenJDK, updating automation processes, testing applications, validating integrations, and reviewing performance. At all stages, we perform thorough testing to ensure applications continue operating as expected after migration. We provide guidance and troubleshooting to make your move from Oracle Java to OpenJDK as stress free as possible.
Knowledge Transfer and Operational Readiness
Before the project concludes, we make sure your team has the skills and documentation needed to support the environment independently. OpenLogic provides documentation, architecture reviews, mentoring, and operational guidance tailored to your environment. We explain configuration changes, maintenance requirements, troubleshooting processes, and upgrade best practices.
By the end of the engagement, your team will be prepared to manage and maintain your OpenJDK environment long after the migration is complete. For teams that need continuing support, we also offer SLA-backed technical support for OpenJDK.

Yes. OpenLogic can help organizations navigate the move from Java EE to Jakarta EE, including the transition of affected packages from the javax.* namespace to jakarta.*.
This change can affect source code, dependencies, frameworks, application servers, build processes, configuration files, and deployment environments. Your project may require upgrades to technologies such Tomcat, Jetty, WildFly, or Spring in addition to OpenJDK itself.
OpenLogic identifies affected Java EE components, maps dependencies, and develops a coordinated migration plan for the full application stack. Our architects can help update namespace references, remediate compatibility issues, upgrade related technologies, and validate the integrated Jakarta EE environment before production deployment.

Before migrating from Oracle Java to OpenJDK, you should understand how Java is used across your environment and what dependencies could be affected by the change. Start by identifying all Oracle Java installations, the applications that rely on them, and the Java versions currently in use.
Next, review application servers, frameworks, third-party libraries, build pipelines, monitoring tools, containers, and operating systems that interact with Java. You should also evaluate performance requirements, security policies, support expectations, and business goals.
For many organizations, an OpenJDK migration represents an opportunity to reduce licensing costs, standardize deployments, modernize applications, or establish a long-term Java strategy. A thorough assessment helps answer critical questions before migration begins:
- Which applications and systems depend on Oracle Java?
- Are there compatibility concerns with frameworks, libraries, or third-party software?
- What testing is required before moving to production?
- Which OpenJDK distribution best fits your support and operational requirements?
- How should the migration be phased to minimize business disruption?
- Are there opportunities to upgrade Java versions as part of the migration effort?
Answering these questions early helps reduce risk, improve project planning, and create a smoother migration path to OpenJDK. Plus, OpenLogic is here to help. Contact us for more information.
Consider migrating when Oracle Java licensing, costs, support terms, or vendor dependence no longer fit your business needs. A migration may also support a broader open source or application modernization strategy. Begin planning before a contract deadline or urgent security concern limits your options. You can read a full comparison of OpenJDK vs. Oracle Java here.
For some applications, moving directly from Java 8 to a supported version can reduce the need for multiple upgrade projects. However, the right path depends on your code, frameworks, libraries, application servers, and operating environment. An assessment can determine whether a direct upgrade or phased approach carries less risk. Contact OpenLogic to learn more.
The compatibility challenges you encounter during a JDK migration depend on your starting version, target version, applications, and dependencies. Common issues include:
- Deprecated or removed Java APIs
- Outdated third-party libraries
- Unsupported framework versions
- Applications that rely on internal Java APIs
- Changes to JVM defaults and security settings
- Build tools, CI/CD pipelines, and automation scripts that need updates
Organizations should also test application performance after migration. Memory usage, startup behavior, garbage collection settings, and runtime performance can change between major Java releases. While these changes often improve performance and security, a structured assessment and testing process helps uncover issues early, reduce risk, and ensure applications are ready for production deployment. Contact us to discuss details on your specific infrastructure.
The timeline depends on the size of your environment, application complexity, target version, dependencies, and testing requirements. Smaller projects may involve a limited set of workloads, while large enterprise environments may require several migration phases. An initial assessment provides a clearer view of scope and effort.
