Migrate at scale in iterations: Use the OpenJDK migration factoryĪs the second largest JDK contributor next to Oracle, Red Hat can help you and your organization build, manage, and scale your applications with the support and services you need.Run pilot migration with a set of applications: Run a representative set of apps has run through the process (changes if any, testing, deployment) and form an updated migration plan.Prepare operational handling (deployment and updates): Get ready operational processes to deploy and manage your JDK.

Analyze applications for potential code changes or risk: Identify in an initial migration plan any areas that represent risk or require change.

Create an inventory of applications and JVMs/versions: Understand existing usage, Oracle licensing, versions, security issues, dependencies, and grouping.

The recommended approach follows five steps. Red Hat and its range of system integration partners have the expertise to facilitate a successful migration to OpenJDK. What can you do to modernize the JDK of your Java applications? Plus, with the newest pricing changes by Oracle, you and your organizations may explore a change to OpenJDK. One caution when evaluating the JDKs: if you are migrating from an older version of OracleJDK, such as Java 8, if an application made use of internal and unspecified APIs, they may not be part of the OpenJDK code base. If it is, migrating to OpenJDK can be beneficial because OpenJDK is the default Java distribution for Linux Ubuntu, Fedora, RHEL, and OpenSUSE distributions. Something else to consider is whether your stack is Linux based. Large organizations may also need to assess their needs for support and stability. Many Java experts encourage users to migrate to OpenJDK as soon as possible, noting that a healthy migration strategy should start with a thorough inventory and risk analysis. Considering the few feature differences, it is up to you to decide which offers more advantages and move forward with the migration.įrom cost to Java support need, there are many factors to consider when considering which JDK to choose.

Between OpenJDK and Oracle JDK, there are no differences in how both JDKs perform with Java SE specification compliant code.
