title: How do I move my existing rails app onto heroku? (sqlite to postgres)
body: <p>I have an existing Ruby on Rails app that already has data loaded into it.</p>
  
  <p>I used the default SQLite database setup, so that is where all my data is located, but I need all my data to go into my Postgres database on heroku.</p>
  
  <p>How do I do that?</p>
