title: SQL Server 2000 : Upgrade from Personal Edition to Enterprise Edition
body: <p>I've never tried this before but this is what I'm attempting to do : </p>
  
  <ul>
  <li>Backup all the databases</li>
  <li>Copy current <code>master.mdf</code> and <code>master.ldf</code> to another location (for later purpose) </li>
  <li>Uninstall SQL Server 2000 Personal Edition</li>
  <li>Install SQL Server 2000 Enterprise Edition (SP4)</li>
  <li>Stop the newly installed server, and replace the <code>master.mdf</code> and <code>master.ldf</code> with those old two files from above </li>
  <li>Restart server </li>
  </ul>
  
  <p>I've done this before, but only with Enterprise Edition, after reinstalling SQL Server I'll just have to replace the master file and everything is fine. </p>
