WebSphere Application Server provides migration tools to help you
to update your configurations and applications to Version 6.0.x.
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 Version 6.0.x product. It is important to use the migration tools for
the version of WebSphere Application Server 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
- Upgrades the client application to a new release level.
- convertScriptCompatibility
- Used by administrators to convert their configuration from a mode that
supports backward compatibility of Version 5.x administration scripts to a
mode that is fully Version 6.0.
- WASPreUpgrade
- Saves the applications and configuration data from a previous installation
of WebSphere Application Server 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
- 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.
You can also use the command to perform a manual migration after installing
the new version.
