How do I undo a heroku create that was run over existing app?

Question

I have been using heroku for deploying my app for a while. I'm at the point where I want to create a new environment for staging. Hoping to solicit usage instructions, I ran heroku create. It turns out this is all that is needed to create an app:

Creating sleepy-chamber-3162... done, stack is cedar
http://sleepy-chamber-3162.herokuapp.com/ | [email protected]:sleepy-chamber-3162.git

I don't think this is what I wanted.

So what have I done? My git branches and history seem to be intact, but I suspect my remote might be pointing to the new app.

How do I undo the changes done by heroku create?

Answer 1

It seems like heroku create creates the new app, but doesn't affect any of the app's files, git metadata, or even default remote paths.

heroku apps:destroy -a sleepy-chamber-3162

seems to be sufficient to undo the create.
