When you use package for an upgrade, the JumpStart program performs the following actions:
All packages already on the system are automatically upgraded.
If you specify package_name add and package_name is not installed on the system, the package is installed.
If you specify package_name delete and package_name is installed on the system, the package is deleted before the upgrade begins.
If you specify package_name delete and package_name is not installed on the system, the package is not installed if the package is part of a cluster that is designated to be installed.
