Migrating product configurations
Use the WebSphere® Application Server Version 9.0 migration tools to migrate your product configurations. These migration tools support migration from Version 7.0 or later.
Before you begin
This topic is about profile configuration migration. To migrate your applications to the latest version, use the WebSphere Application Server Migration Toolkit.
Read Overview of migration, coexistence, and interoperability and Migration considerations. For resources to help you plan and perform your migration, visit Knowledge Collection: Migration planning for WebSphere Application Server.
Migration Source (Version 7.0 or later) | WebSphere Application Server Version 9.0, with Stand-alone and Custom Profiles as the target |
---|---|
WebSphere Application Server (base) stand-alone application server | Supported |
WebSphere Application Server Network Deployment stand-alone application server | Supported |
WebSphere Application Server Network Deployment federated application server | Not supported |
WebSphere Application Server Network Deployment deployment manager | Not supported |
WebSphere Application Server Client | Not supported |
Migration Source (Version 7.0 or later) | WebSphere Application Server Version 9.0, with the deployment-manager management profile as the target |
---|---|
WebSphere Application Server (base) stand-alone application server | Not supported |
WebSphere Application Server Network Deployment stand-alone application server | Not supported |
WebSphere Application Server Network Deployment federated application server | Not supported |
WebSphere Application Server Network Deployment deployment manager | Supported |
WebSphere Application Server Client | Not supported |
You can migrate your product configurations using the WebSphere Application Server Version 9.0 Migration wizard or the command-line migration tools.
Before using the migration tools, consult the IBM WebSphere Application Server supported hardware, software, and APIs website 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.
- 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:
Procedure
-
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.
- Stop the nodeagent process before you migrate the nodes.
- Stagger the start of the migration process for each node by 3 to 5 minutes.
-
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.
