title: Heroku Migrate Database Changes
body: <p>I've made changes to my app, including adding models and adding columns to a pre-existing model. I'm using rails 3.1 and I'm aware that I must precompile my assets before deploying. Once I run <code>git push heroku master</code> and <code>heroku rake db:migrate</code> should I expect any errors? </p>
  
  <p>I'm trying keep downtime to a minimum because users be interacting with the site during deployment. </p>
  
  <p><strong>Update</strong></p>
  
  <p>Everything seems to be fine. Push &amp; Rake DB did it. </p>
