It is generally recommended that all Java ES components on a computer system (and in a computing environment) be upgraded to Release 5U1. However, the upgrade of Web Proxy Server to Release 5U1 only requires that Windows Installer patch (126910–02) is already applied.
The Web Proxy Server upgrade to Release 5U1 does not modify the Release 5 configuration data. There is no need to back up current data.
