As technology advances, particularly in the area of Java components, new WebSphere Application Server product versions advance to support and extend the most recent open specification levels. If your existing applications currently support different specification levels than are supported by WebSphere Application Server - Express, it is likely you need to update at least a few aspects of the applications to comply with the new specifications.
Note: Evaluate the Deprecated Version 5.1 items before you migrate your applications.
