Scenario 2: Migrating cells across operating systems using the command-line tools

Before you begin

Review the migration planning information. See Knowledge Collection: Migration planning for WebSphere® Application Server.

About this task

This task describes how to use the command-line tools to migrate cell topologies across operating systems from a previous version of WebSphere Application Server to Version 7.0 Fix Pack 7 or later. The cell configuration consists of a deployment manager with one or more nodes, a web server, and an application client. All ports are migrated forward into the new configuration. This procedure assumes that the previous configuration is running and that you are migrating all profiles to a new host.

Procedure

  1. Run the backupConfig command on the deployment manager and all old nodes
  2. Install WebSphere Application Server Version 7.0
  3. Upgrade the WebSphere Application Server Version 7.0 supplemental CD to the desired fix pack level
  4. Create the target deployment manager profile
  5. Run the WASPreUpgrade command from the updated WebSphere Application Server supplemental CD
  6. Verify the console output and the WASPreUpgrade logs for success, warnings, or failure
  7. Archive the backup directory created by the WASPreUpgrade command
  8. Run the WASPostUpgrade command from the new deployment manager profile bin directory
  9. Verify the logs for success
  10. Run the backupConfig command on the Version 7.0 deployment manager
  11. Stop and disable the deployment manager on the old host.
  12. Start the Version 7.0 deployment manager
  13. Manually synchronize all nodes
  14. Migrate plug-ins for web servers
  15. Run a migration on application client installations
  16. Migrate nodes
  17. Troubleshoot

Results

You have migrated from a previous version to WebSphere Application Server Version 7.0 Fix Pack 7 or later using the migration tools.
