title: How can I test DB2 9.5 -> 9.7 Migration/Upgrade?
body: <p>I am going to migrate a DB2 9.5 database into DB2 9.7. I hope that it will be a smooth process. But I want to be sure that the applications are not affected in a negative manner.
  <br>"you can run your application and see if everything works" would be a way to ensure the database functionality needed. 
  What I want to know is</p>
  
  <ul>
  <li>Is there any subject/DB2 functionality that I need to pay particular attention to.</li>
  <li>What is the best testing way that I can choose.</li>
  <li>Is there a functionality that improves the performance that i must add to my old DB Structure.</li>
  </ul>
  
  <p>Any help will be welcome..</p>
