title: single SSIS package with multiple package configurations
body: <p>I have an SSIS package with 2 package configurations (Configuration1 and Configuration2) with configuration locations stored in 2 different enviornment variables. Which configuration has to be used is decided based on the value of a variable (<code>@type</code>) passed at run time.</p>
  
  <p>That is , use Configuration1 when <code>@type ='override'</code> and
  use Configuration2 when <code>@type ='overload'</code>.</p>
  
  <p>How can I do this in SSIS?</p>
