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 for z/OS Version 6.1.x Target
Standalone Application Server Federated Application Server Deployment Manager
WebSphere Application Server for z/OS Version 5.x or 6.0.x standalone application server Supported    
WebSphere Application Server for z/OS Version 5.x or 6.0.x federated application server   Supported  
WebSphere Application Server for z/OS Version 5.x or 6.0.x deployment manager     Supported
WebSphere Business Integration Server Foundation for z/OS Version 5.1.x standalone application server Supported *    
WebSphere Business Integration Server Foundation for z/OS Version 5.1.x federated application server   Supported *  
WebSphere Business Integration Server Foundation for z/OS Version 5.1.x deployment manager     Supported *
* WebSphere Application Server for z/OS Version 6.1.x supports the migration of a subset of programming model extensions (PMEs) from WebSphere Business Integration Server Foundation. See Programming model extension migration for more information on this support.

Use this article as a starting point for the planning information, information on creating your migration jobs, as well as specific migration explanations for standalone application server nodes, deployment managers, and federated nodes.

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.

Best practice Best practice: The deployment manager maintains the master configuration data for all of the nodes that it manages. This configuration data is updated through the configuration manager. When the configuration manager detects that the updates to the configuration data were not made against the latest saved copy, it reject the updates and creates an exception. To avoid this situation, following these best practices:
  • Migrate each node independently. For example, let the first node complete the migration process before starting the process for the second node, and so on.
  • Ensure that the administrative console for the deployment manager is not running when the migration process is in progress.
If you need to migrate federated nodes concurrently, use the following steps to minimize the potential failures:
  1. Run the backupConfig command for the deployment manager and each federated node before you begin. For more information, see the documentation about the backupConfig command.
  2. Stagger the start of the migration process for each node by 3 to 5 minutes.
  3. Run the restoreConfig command on that node and rerun the migration process if a failure occurs. For more information, see the documentation about the restoreConfig command.

Procedure

You can perform the following actions.
  1. Migrate a standalone application server node to WebSphere Application Server Version 6.1.x.

    See Migrating standalone application servers for more information.

  2. Migrate a deployment manager to WebSphere Application Server Version 6.1.x.

    See Migrating deployment managers for more information.

  3. Migrate a federated node to WebSphere Application Server Version 6.1.x.

    See Migrating federated nodes for more information.

  4. Migrate your Web server plug-ins to work with WebSphere Application Server Version 6.1.x.

    See Migrating Web server configurations for more information.
