5. Run `bundle exec rake db:migrate RAILS_ENV=production` to update your old database to the new schema. This is the point of no return. Make sure you have backups!
6. Precompile your static assets (css, javascript, etc.) by running `bundle exec rake assets:precompile RAILS_ENV=production`.
7. Run `bundle exec rails server -e production` inside your Tracks 2.3 directory to start up Tracks. Or use `-e development` if you intend to try your changes and get more log info.
Please note that if you intend to use Tracks with the built in webserver called WEBrick for production, you’ll need to change `config.serve_static_assets` to `true` in `config/environments/production.rb` in order for the images, stylesheets, and javascript files to be served correctly.
