This chapter describes how to upgrade Portal Server from Java ES 5 (Release 5) to Java ES 5 Update 1 (Release 5U1).
The version of Portal Server included in Java ES Update 1 is the same as that included in Java ES 5 and so no upgrade patches are provided for upgrading Portal Server from Release 5 to Release 5U1.
On a Java ES 5 setup that has Portal Server on Web Server, upgrading Web Server to Java ES 5 Update 1 level renders Portal Server as unusable. Release 5U1 Web Server uses JSF 1.2. But JSF-Portlet bridge in Release 5 Portal Server does not support JSF 1.2. So Portal Server will not work. Do not upgrade Web Server to Release 5 Update 1 in case you want to continue using Release 5 Portal Server.
