Upgrading your existing vRealize Hyperic installation to the most recent version provides you with access to the latest features and enhancements. If you have been using a database other than vPostgreSQL, you must migrate it to continue access to its data.
The installer installs a new version of vRealize Hyperic, configuring the new server instance based on the configuration information from your previous server installation configuration files.
If you use the vRealize Hyperic internal database, the installer creates a new database instance that contains the data from the existing instance. The new instance has an updated schema. The PostgreSQL server is not upgraded to a new version.
If you use an external database, the installer updates the existing instance.
