Chapter 3. Preparation for migration
Red Hat build of OpenJDK 11 includes changes that might require you to reconfigure your applications, which were already successfully deployed on Red Hat build of OpenJDK 8.
You can ensure an effective migration plan by completing the following tasks:
- Review the Major differences between Red Hat build of OpenJDK 8 and Red Hat build of OpenJDK 11 section.
- Integrate the differences into your migration plan.
Red Hat provides a migration toolkit for applications (MTA) tool that you can use to help with your migration tasks. You can use the MTA tool to migrate Java applications from Red Hat build of OpenJDK 8 to Red Hat build of OpenJDK 11.
