Migration wizard GUI to the primary v8.0 migration tools: WASPreUpgrade and WASPostUpgrade. Cannot run in a non-graphical environment such as telnet sessions.
WASPreUpgrade Save application and configuration data from a previous installation of WAS to a backup directory. The WASPostUpgrade tool restores the configuration data from the directory to the new installation.

clientUpgrade Upgrade client applications to a new release level.
convertScriptCompatibility Convert their configuration from a mode that supports backward compatibility of v6.x or 7.x administration scripts to a mode that is fully v8.0.
convertSelfSignedCertificatesToChained Use with wsadmin.sh to convert self-signed certificates to chained certificates, which are the default certificate type in WAS v8.0.
