cannot rename name apps of cli in heroku

Question

I´m trying to rename apps of cli, but I get the error, that No app specified.

I done

heroku create
heroku apps:rename newname

Answer 1

It says: run this command from an app folder.
To do this you have to clone the app first. Then go into the app folder and run your command again.
Or just specifiy the app via --app oldname:

heroku apps:rename newname --app oldname
