Migration support consists of tools that are shipped as part of WebSphere Application Server V6.1 that primarily provide support for saving the configuration and applications from an older version of WebSphere into a migration-specific backup directory and then importing that configuration into V6.1.

See...

• Overview of migration, coexistence, and interoperability
• Premigration considerations

Use the migration tools for the version of WebSphere Application Server that you are installing. The tools change over time. If you use migration tools from an earlier release of WebSphere Application Server, you are likely to encounter a problem with the migration.

All of the migration scripts are in the app_server_root/bin directory after installation.

Procedure

WASPreUpgrade tool

Saves the applications and configuration data from a previous installation of WebSphere Application Server to a backup directory.

WASPostUpgrade tool

Restores the configuration data from a previous release.

The WASPostUpgrade tool reads the data from the backup directory where the WASPreUpgrade tool stored the data.

clientUpgrade tool

Upgrades the client application to a new release level.

convertScriptCompatibility tool

Used by administrators to convert their configuration from a mode that supports backward compatibility of V5.x or 6.0.x administration scripts to a mode that is fully V6.1.
