Upgrading CloudStack
====================

Java version upgraded to Java 17
---------------------------------

As of Apache CloudStack 4.20, support for running with Java 17 has been added.
In later versions, support for Java 11 will be removed.

If you are running CloudStack with Java 17, for CloudStack versions 4.20 and later:
  * Verify /etc/default/cloudstack-management is consistent with https://github.com/apache/cloudstack/blob/main/packaging/systemd/cloudstack-management.default; Specifically, ensure that the following is present in the JAVA_OPTS:

  .. code-block:: bash

   --add-opens=java.base/java.lang=ALL-UNNAMED --add-exports=java.base/sun.security.x509=ALL-UNNAMED

  * Verify /etc/default/cloudstack-usage is also consistent with the same file in the repository.
  * Perform the same check for /etc/default/cloudstack-agent on the hypervisor hosts.
