Rolling back the migration upon failure

You can roll back a failed migration. Use the restoreConfig.sh command (or the restoreConfig.bat command for Windows) supplied with WebSphere Application Server 6.0, located in the %WAS_HOME%/bin directory, to return the 6.0 profile to its previous state.
Issue the restoreConfig command with a single argument, the location of the backup zip file created with the WebSphereProcessServerPreUpgradecommand, as shown in the following example:
C:\IBM\WebSphere60\AppServer\profiles\AppSrv01\temp\MigrationBackup.Thu-Dec-16-18.28.13-2004.zip
Note: If the -backupConfig option is set to false when invoking the WebSphereProcessServerPreUpgrade command, rolling back is not possible.
