title: What's wrong with this ruby on rails migration?
body: <p>I am trying to migrate ruby on rails application from one machine to another and when I type 
  Rake db:migrate it gives following error:</p>
  
  <pre><code>Mysql::Error: Table 'schema_migrations' already exists:
  CREATE TABLE `schema_migrations` (`version` varchar(255) NOT NULL) ENGINE=InnoDB
  </code></pre>
