I have upgraded Oracle Application Testing Suite from version 9.31.0036 to 126.96.36.199.0 successfully. After which, on login to Administrator console with pre-defined user details it shows message "The Oracle Test Manager database you are connecting to is an old version and must be updated. would you like to update now ?". But when I click on ‘Yes’, it shows message "The Oracle Test Manager database could not be updated. Please make sure that the user has Administrator rights for the database and the password entered is correct."
Hum it reminds me something I cannot find anymore...
Solution was (hopefully my brain is not totally mad) to use the Database Configuration Assistance to do so (from the OATS Admin start menu).
Try that and let us know
