title: Migrating to Identity AspNetUsers
body: <p>I added <code>Identity</code> in my new MVC project, I have <code>DB</code> that have basic <code>Account</code>, <code>Customers</code> etc. tables that are used in WPF app. It all works now, registered users are added in <code>AspNetUsers</code> table... But my <code>DB</code> is useless.  </p>
  
  <p>Now I have 1000 Accounts with <code>Id</code> that is auto increment integer, <code>MobileNumber</code> and <code>Passwords</code>. How can I migrate all that in <code>AspNetUsers</code>, or better can I switch to my table and not use <code>AspNetUsers</code> table with String as Id because my other tables work with <code>Account</code> table? </p>
