Use the migration tools to migrate your applications and configuration from WebSphere Application Server - Express Version 5.x to Version 6.0.x.
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 configuration information for the Version 5.x Express server resources, security, variables, and virtual hosts to the Version 6.0.x base product. All stored information is in XML files in the profile_root/config/cells directory of each product.
Later, the Migration wizard uses the WASPostUpgrade migration tool to restore the environment in the backup directory into the base WebSphere 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 tools log a message that states you must manually resolve the port conflict.
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.
