Migrating product configurations

Use the WebSphere Application Server Version 6.1.x migration tools to migrate your product configurations. These migration tools support migration from WebSphere Application Server Version 5.x and Version 6.0.x.

Before you begin

See Overview of migration, coexistence, and interoperability and Premigration considerations.

The following configuration upgrades of WebSphere Application Server versions and offerings are directly supported.
Table 1. Directly Supported Configuration Upgrades
Migration Source WebSphere Application Server Version 6.1.x Target
Base Standalone Profile
WebSphere Application Server Version 5.x or 6.0.x base standalone application server Supported
WebSphere Application Server Version 5.x or 6.0.x Network Deployment standalone application server Supported
WebSphere Application Server Version 5.x or 6.0.x Network Deployment federated application server Supported
WebSphere Application Server Version 5.x or 6.0.x Network Deployment deployment manager  
WebSphere Application Server Version 5.x or 6.0.x Express standalone application server Supported

You can migrate your product configurations using the WebSphere Application Server Version 6.1.x command-line migration tools.

Before using the migration tools, consult the WebSphere Application Server Version 6.1.x Release Notes document to understand what fixes you must apply to earlier versions. Applying fixes to an earlier version might also apply fixes to files that have a role in the migration. Apply any fixes to ensure the most effective migration of configurations and applications.

About this task

When you use the migration tools, the overall migration process includes these steps:
  1. Install the WebSphere Application Server Version 6.1.x product.

    Installing the product creates a standalone application server.

  2. Use the migration tools to migrate the previous release to the WebSphere Application Server Version 6.1.x product.

    See Using the migration tools to migrate product configurations.

The WASPreUpgrade command saves the configuration and applications of the previously installed version of WebSphere Application Server into a migration-specific backup directory. The WASPostUpgrade command uses the backupConfig command to save the existing Version 6.1.x configuration before performing migration, and the results are stored in the profile_name/temp directory. You can use the restoreConfig command to restore the backup if required.

For help in troubleshooting problems when migrating, see Troubleshooting migration.

Procedure

Perform the following actions.
  1. Migrate the WebSphere Application Server Version 5.x and Version 6.0.x standalone application server nodes.
    Select one of the following migration scenarios for information about how to migrate configuration data to a Version 6.1.x standalone application server:
  2. You might want to do some things that are not done automatically by the migration tools.
    • Perform any of the following non-automated tasks:
      • Migrating from Version 5 embedded messaging
    • Examine any Lightweight Third Party Authentication (LTPA) security settings that you might have used in WebSphere Application Server Version 5.x or 6.0.x, and make sure that Version 6.1.x security is set appropriately.
    • Check the WASPostUpgrade.log file in the logs directory for details about any JSP objects that the migration tools did not migrate.

      If Version 6.1.x does not support a level for which JSP objects are configured, the migration tools recognize the objects in the output and log them.

    • Configure WebSphere Application Server to use a database.

      For example, you can configure WebSphere Application Server to use DB2.

  3. Use Configuration mapping during product-configuration migration to verify the results of the migration.

    The article has a detailed description of how the migration tools migrate objects and what you should verify.
