Hi Charels,
GSS 2.0 can be upgraded from Ghost 8.0 or later (GSS 1.0 & 1.1). Ghost Console settings (include tasks, configuration settings, customized inventory filters etc) will be carried into GSS 2.0.
You may like to take a copy of the database yourself before upgrading just in case, which the upgrade process should do. You need to stop the DBservice before copy c:\program files\symantec\ghost\db
Thanks,
Jenny
