Can you save the case file in fluent as an older version?

 It's not possible to save a case file in Fluent as an older version. Fluent does not support backward compatibility. This means that once a case file has been saved in a newer version of Fluent, it cannot be opened in an older version of Fluent. If you need to use an older version of Fluent, you would need to recreate the case in that version.
