title: Changing passwordFormat from Encrypted to Hashed
body: <p>I'm finding surprisingly little information on converting an existing database from Encrypted passwords to Hashed passwords. (I was able to find a bit more information on converting the other way, but it wasn't of much help.)</p>
  
  <p>As most people know, changing the <code>passwordFormat</code> setting in web.config only affects new users. I have a database with a couple of hundred users and I'd like to convert them to use hashed passwords without changing those existing passwords.</p>
  
  <p>Is anyone else familiar with how one might approach this? Thanks for any tips.</p>
