Use the migration tools to migrate your applications and configuration from WebSphere Application Server - Express Version 5.x to a standalone application server in the Version 6.0.x Network Deployment product.
The Migration wizard uses the WASPreUpgrade command-line tool and the WASPostUpgrade command-line tool to migrate the data and applications from Version 5.x to Version 6.0.x.
This step transfers applications and configuration information for the Version 5.x Express server resources, security, variables, and virtual hosts to the Version 6.0.x standalone application server. All stored information is in XML files in the app_server_root/config/cells directory of each product. For a full description of each XML file, see the Configuration documents and Configuration document descriptions articles in the information center.
Later, the Migration wizard uses the WASPostUpgrade migration tool to restore the environment in the backup directory into the Version 6.0.x standalone application server installation.
The Migration wizard displays a list of ports for Express. If the same port is used for more than one purpose, the Migration wizard will print a warning message (with a prefix ending in "W:"). This message signifies that a custom port from the Version 5.x Express configuration is part of the default Version 6.0.x destination profile. The Migration wizard does not resolve these port conflicts automatically; it gives a warning that the server might not function properly until the port conflicts are resolved.
There are a number of special purpose ports defined for Express. These ports are described in the Migrating and coexisting article. Use non-conflicting values to continue to run both Version 5.x Express and Version 6.0.x Express on the same system (coexistence), or if WebSphere Application Server applications are dependent on the port values.
Using Version 6.0.x Express port values might require you to change applications. Change any references to port values that are changing. To identify Express applications that require port changes, modify the port configuration on the Version 5.x Express installation to use Version 6.0.x port values. Test the applications that you intend to migrate to identify port references that are in error.
