How to run DB migrations that effect only on heroku fork app

On heroku I create fork app using heroku fork --from sourceapp --to targetapp

By this I copy an existing application and Heroku Postgres data.

Now I push some migrations on fork app using git push forked master.

How I run these migrations on heroku that it effect only heroku-fork app.

When I run heroku run rake db:migrate , is it effect both or only fork one?

When you have multiple applications associated with the same codebase, Heroku will ask you which application you want to run the command on.

You'll specify that with the -a or --app flag, so for example

heroku run rake db:migrate --app <APPNAME>

This will allow you to run commands on the fork app or the source app.
