This product edition contains several programming model extensions (PMEs) that previously were available only by obtaining a different product edition.
The migration of PME services to WebSphere Application Server Version 7.0 is handled on an individual basis. For PME services that are not supported in WebSphere Application Server Version 7.0, all configuration information is removed. For PME services that are supported in WebSphere Application Server Version 7.0, the configuration from the previous release environment overwrites the values in the new release.
As part of application installation, both during migration and outside of migration, applications are validated to ensure that they only use resources for services that are supported by WebSphere Application Server Version 7.0. Any application that uses a resource for a service that is not supported by WebSphere Application Server Version 7.0 will not work correctly, and an error will be issued indicating that the application cannot be installed.
