title: How to install DotNetNuke so I can migrate existing users?
body: <p>I'm doing a fresh install of DNN 6.0.</p>
  
  <p>I have an existing 4.x site with thousands of users, and my goal is to copy the users from the old database to the new one with some SQL queries. Of course the two sites must have the same machineKey.</p>
  
  <p>I thought I had to set the machineKey value <strong>before</strong> running the installer, but then installation process overwrites it.</p>
  
  <p>If I change the machineKey <strong>after</strong> running the installer, I can't access the host login created during the install process.</p>
  
  <p>What am I missing?</p>
  
  <p>I'm willing to use a third-party migration tool, but note that I'm not moving users between <em>portals</em>, I'm moving them between <em>websites</em>.</p>
  
  <p>If it matters, I'm using SQL Server on Windows 2003.</p>
