Is there a way to get the old version of .tas file back, once it has been upgraded in Toad (4318695)

When trying to open a .tas file recently migrated from an old version of Toad Data Point, it shows the following message:

  "You opened a script that was created using a previous version of Automation". 

  If there are some .TAS (Toad Automated Script) files migrated from an older version of Toad Data Point  and it seem they are not working  as expected into the newer version.

Is it possible to downgrade or just get the old version of  the .tas back  from the newer version and make them work in the older version ? 

Toad Data Point keeps a shadow copy of the automation script before to migrate them to the newer version. 

Steps:

1.  Start up the newer version of Toad Data Point

2.  Go to Help | About | Application Data Directory  (click on Application Data Directory)

3.  Click on Automation |  Bak folder  >>  It will show the .tas files before to migrate.
