Migrating application programming interfaces (APIs) and specifications involves moving to the current Java component level as well as to other technologies that WebSphere Application Server Version 6.0.x supports.
Migrating APIs and specifications also includes moving to the most contemporary open specification levels. If your existing applications currently support different specification levels than those supported by this product version, you should review your applications for required changes to comply with the new specifications.
