Installing a new version of the ChorusOS operating system will not overwrite an existing version. Therefore, it is not necessary to back up any files or directories relating to the previous version before installing the new version. It is also unnecessary to uninstall the existing version, since the installation directory depends on the release number and will be different to the existing installation directory.
The correct version of JVM must be installed on the host before you install the ChorusOS operating system.
For complete instructions on installing version 5.0 of the ChorusOS operating system, refer to the ChorusOS 5.0 Installation Guide.
