Chapter 4. Upgrading CodeReady Studio
The following section describes the possibilities of upgrading your version of CodeReady Studio to the latest major and minor versions.
4.1. Upgrading major versions of CodeReady Studio
Each major version of CodeReady Studio is based on a different version of Eclipse. As a result, it is not possible to upgrade an older major version of CodeReady Studio to a newer major version. For example, it is not possible to update a CodeReady Studio 10.x installation to 11.x. However, it is possible to use the workspaces created using CodeReady Studio 11.x with CodeReady Studio 12.x.
Note that you can have multiple versions of CodeReady Studio installed on your system with Installer or Eclipse, provided you have these versions located in different directories.
The following table details the Eclipse versions supported with each major version of Red Hat CodeReady Studio:
