how to delete heroku app and switch to the new app created from the same files?

Question

I am using Heroku toolbelt:

1. Command line: >heroku create app1 (root application)
2. Delete app1 from Heroku Dashboard in the browser.
3. Command line: >heroku create app2 (from the same root application)

4. I wanted to add variable: heroku config:set MYVAR=value

   Then I get the error:

   Setting MYVAR and restarting app1... !
    !    Couldn't find that app.
   

How can I switch to the new app (app2) and remove app1 completely?

Answer 1

 heroku apps:destroy --app app1 --confirm app1

 heroku git:remote -a app2

Answer 2

You can change the app from app1 to app2 by using

heroku git:remote -a app2

Answer 3

Try destroying the old app:

heroku apps:destroy app1

Note that this will permanently and irrevocably destroy app1.
