[V5.1 and later]Migration tools

This topic introduces the migration tools that WebSphere Application Server provides. All of the migration tools are in the install_root/bin directory after installation. The WASPreUpgrade.sh or WASPreUpgrade.bat scripts also ship in the /migration/bin directory on the product CD-ROM so that you can store the configuration of an existing release before installing the V5.1 product. It is important to use the migration tools for the version of 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 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 Application Server, you are likely to encounter a problem with the migration.

clientUpgrade.sh (and clientUpgrade.bat)

Upgrades the client application to a new release level.

pre_uninst50ws.sh (and pre_uninst50ws.bat)

Prevents a federated node that you migrate to a new version, from removing the new node from the cell when you uninstall the old node.

post_uninst50ws.sh (and post_uninst50ws.bat)

Restores the normal uninstaller environment that allows the uninstaller to remove a base node from a cell prior to uninstalling the base node.

pre_uninst502mq.sh (and pre_uninst502mq.bat)

Prevents the uninstaller from uninstalling the embedded messaging feature and the message queue when it uninstalls a V5.0.2 node that you have migrated to V5.1.

post_uninst502mq.sh (and post_uninst502mq.bat)

Restores the normal uninstaller environment that allows the uninstaller to uninstall a base V5.0.2 node and delete the embedded messaging feature and its queue manager.

WASPreUpgrade.sh (and WASPreUpgrade.bat)

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 installer calls the WASPreUpgrade.sh script during installation, if you select migration. You can also use the command to perform a manual migration, after installing the new version.

WASPostUpgrade.sh (and WASPostUpgrade.bat)

Restores the configuration data from a previous release. WASPostUpgrade reads the data from the backup directory where the WASPreUpgrade script stored the data. The installer calls the WASPostUpgrade.sh script during installation, if you select migration. You can also use the command to perform a manual migration, after installing the new version.
