Use the WAS migration tools to help you to update your configurations and applications to v6.x.
About this task
All of the migration tools are in the app_server_root/bin directory after installation. The WASPreUpgrade command also ships in the /migration/bin directory on the product CD-ROM so that you can store the configuration of an existing release before installing the v6.x product. It is important to use the migration tools for the version of WAS that you are installing. The tools change over time. The tools on the product CD-ROM provide the necessary function for migrating from a previous release of WebSphere Application Server to the one on the product CD-ROM. The tools on the CD-ROM match the product on the CD-ROM. If you use migration tools from an earlier release of WebSphere Application Server, you are likely to encounter a problem with the migration.
- clientUpgrade command
Upgrades the client application to a new release level.
- convertScriptCompatibility command
Used by administrators to convert their configuration from a mode that supports backward compatibility of V5.x administration scripts to a mode that is fully v6.
- WASPreUpgrade command
Saves the applications and configuration data from a previous installation of WAS to a backup directory. The WASPostUpgrade script restores the configuration data from the directory to the new installation. The Migration wizard calls the WASPreUpgrade command during migration. You can also use the command to perform a manual migration after installing the new version.
- WASPostUpgrade command
