Migration tools

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 we 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.

 

Procedure

• 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. We can also use the command to perform a manual migration after installing the new version.

• WASPostUpgrade command

  Restores the configuration data from a previous release. The WASPostUpgrade command reads the data from the backup directory where the WASPreUpgrade script stored the data. The Migration wizard calls the WASPostUpgrade command during migration. We can also use the command to perform a manual migration after installing the new version.

• Migration wizard

  Migrates an earlier supported version of WAS to v6.x.
