As far as I'm aware there isn't. Comparing metadata between major SAS releases would be like comparing chalk and cheese - very different!
If the purpose of comparing metadata is to prove that your new SAS 9.4 environment is set up correctly, only testing all migrated SAS applications will do that.
How many stored processes have you got? How about using two SAS Management Console sessions, one 9.3 the 9.4 and then just going through the metadata folders, verifying all stored processes are present in 9.4?
I have completed the task by exporting the package which includes the stored process and then comparing it in an excel sheet.
