Presumedly you mean TMG...yes backup files for floppies can be imported into TMG. They will be read and your project will be restored in a temporary folder and then imported into TMG. However, TMG can import directly from your UFT project. I take it you have not been able to restore your backup after upgrading and therefore only have the backups to import into TMG.
UFT does run under TMG...maybe others here can respond. Could you be more specific as to why UFT is not working? Does it not install? Are you unable to open your backup? Do you get an error message when trying to run UFT and if so what is it?
