This is based on Russell's answer but a bit more aesthetic and functional for forms. jQuery:

$(document).ready(function(){
   var cur_num = 1;    // Counter

    $('#btnClone').click(function(){

          var whatToClone = $("#MainConfig"); 
          var whereToPutIt = $("#smallConfig");

          var cloned = whatToClone.clone(true, true).get(0);
          ++cur_num;
          cloned.id = whatToClone.attr('id') + "_" + cur_num;                  // Change the div itself.

        $(cloned).find("*").each(function(index, element) {   // And all inner elements.
          if(element.id)
          {
              var matches = element.id.match(/(.+)_\d+/);
              if(matches && matches.length >= 2)            // Captures start at [1].
                  element.id = matches[1] + "_" + cur_num;
          }
          if(element.name)
          {
              var matches = element.name.match(/(.+)_\d+/);
              if(matches && matches.length >= 2)            // Captures start at [1].
                  element.name = matches[1] + "_" + cur_num;
          }

         });

       $(cloned).appendTo( whereToPutIt );

    });
});
