Problems with Suse 8.1 Autoinstall (conversion problems)

Hello Under Suse 8.0 Professional we have made an autoyast xml file. But under Suse 8.1 Pro it isn`t possible to import all options from the Suse 8.0 xml file. If we import the old xml file and saved it after the import, under the newer autoyast some of the options were gone. How can I easily convert the Suse 8.0 xml file to 8.1? Is there an included script, a file or an option in the new autoyast. Greerings and thanx Tobias
