Product Component Upgrade Approaches
The upgrade of each product component involves one of the upgrade approaches described in the following sections:
Performing a Fresh Install of the Component
Java ES 5 product components are upgraded by performing a fresh install of the components using the Java ES installer. You should install Release 5 in a parallel path and leave the previous version intact. You can reconfigure the product component by migrating the previous version's configuration data to the new installation, or by performing a new configuration, or by doing a combination of both. For some product components a utility is provided for reconfiguring or migrating configuration data for the component.
Patching Existing Component Packages
Web Proxy Server upgrade is performed by manually patching the existing software packages. For more information, see To Upgrade Web Proxy Server.
