This page describes the minimum product levels you should have installed before opening a problem report with the WebSphere Application Server support team. Because other products frequently ship fixes, updates, and new releases, we cannot test every possible configuration. In general, you can install and run with updates to supported products if those updates are forward compatible. For additional information on available support for configurations that do not appear in the following list, click here.
