Migration tools

This topic introduces the migration tools that WAS 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 V6 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.

convertScriptCompatibility.sh (and convertScriptCompatibility.bat)

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 V6.0.

WASPreUpgrade.sh (and WASPreUpgrade.bat)

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.sh script during migration. We 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 Migration wizard calls the WASPostUpgrade.sh script during migration. We can also use the command to perform a manual migration, after installing the new version.
