Migrating product configurations

Use the WebSphere® Application Server Version 8.5 migration tools to migrate your product configurations. These migration tools support migration from Version 6.1 or later.

Before you begin

Supported configurations:

This topic is about configuration migration, such as migrating deployment managers and federated nodes in a network deployment environment. The Application Migration Toolkit for WebSphere Application Server provides support for migrating applications from previous versions of WebSphere Application Server to the latest product version. For information about migrating applications, read more about the Migration Toolkit.

Read Overview of migration, coexistence, and interoperability and Premigration considerations. For resources to help you plan and perform your migration, visit Knowledge Collection: Migration planning for WebSphere Application Server.

[AIX Solaris HP-UX Linux Windows]You can migrate your product configurations using the WebSphere Application Server Version 8.5 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.

Procedure

  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: backupConfig command
  2. Stop the nodeagent process before you migrate the nodes.
  3. Stagger the start of the migration process for each node by 3 to 5 minutes.
  4. 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: restoreConfig command
