title: Convert MySQL tinyint types to bit
body: <p>I used the MySQL Migration Toolkit to migrate a SQL Server 2008 database to MySQL. However, it converted all my <code>bit</code> types to <code>tinyint</code>. My data model doesn't like this, because I have a bunch of expressions testing for true/false, and not 0-255.</p>
  
  <p>Is there a way to tell the Toolkit to convert these different, or some SQL I can run on the new database to convert?</p>
