Use the following setup (example for version 13.0 and 12.10):
1) Toad does create some folder structure during the first run. In this situation has to be created manually. Create a "Quest Software" folder, manually create the "SettingsLocations.ini" file in the location where it would be created by Toad for Oracle 13.10.
2) In the "SettingsLocations.ini" file create the following content:
[TOAD 13.0]
MigrateFrom=<path>
Where <path> is AppData folder you can find in section [12.10] in the old SettingsLocation.ini (located in the old location).
3) Start Toad for Oracle.
Now you should see imported settings.
Step 2 requires some scripting on your side (parse the old SettingsLocation.ini file and create a new one in a new location).
