This topic describes the movement of a subset of PMEs to WebSphere Application Server Version 6 from WebSphere Application Server Enterprise Edition V4.0.x and V5.0.x and WebSphere Business Integration Server Foundation V5.1.x.
Overview of PME migration
The migration of PME services from WebSphere Application Server Enterprise Edition V4.0.x and V5.0.x and WebSphere Business Integration Server Foundation V5.1.x to WebSphere Application Server Version 6 is handled on an individual basis. For PME services that are not supported in WebSphere Application Server V6, all configuration information is removed. For PME services that are supported in WebSphere Application Server V6, the configuration from the previous release environment overwrites the values in the new release.
Validating PMEs
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 V6. Any application that uses a resource for a service that is not supported by WebSphere Application Server V6 will not work correctly, and an error will be issued indicating that the application cannot be installed.
Running a mixed-node environment
When running in a mixed node environment (such as a WebSphere Application Server V6 deployment manager managing WebSphere Business Integration Server Foundation V5.1.x nodes), the first syncNode performed by the system downloads a configuration from the WebSphere Application Server V6 deployment manager to the WebSphere Business Integration Server Foundation V5.1.x nodes. Therefore, any PME service that is not supported by WebSphere Application Server V6 will be rendered inoperable on the WebSphere Business Integration Server Foundation V5.1.x node.
