Is there a way to use 2 jQuery libraries at once?

Is there a way to use 2 jQuery libraries at once?

I am trying to use the Flexslider2 plug-in on a website that is using the 1.3.2 library; the slider only works with versions 1.4.2+.  If I reference a newer library, other functionality on the site breaks.

I don't have the ability to update the reference to the 1.3.2 library, or modify that piece of the site at all; only update a "zone" on a page via a CMS.  These are the scripts I'm using in that zone which is resulting in an error that says
TypeError: slider.slides.first is not a function 
var slide = slider.slides.first(),


and the slider doesn't work.   I am new to jQuery so any help in getting the new AND the old libraries to play nicely together would be greatly appreciated.  Thank you.

<!-- load jQuery 1.8.3 -->
<script type="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript">
var jQuery_1_8_3 = $.noConflict(true);
</script>
<script type="text/javascript" src="../js/jquery.flexslider.js"></script>
<script type="text/javascript">
    $(window).load(function() {
      $('.flexslider').flexslider({
        animation: "slide"
      });
    });
</script>














I also tried the last script tag this way:
<script type="text/javascript">
    jQuery_1_8_3(window).load(function() {
      jQuery_1_8_3('.flexslider').flexslider({
        animation: "slide"
      });
    });
</script>







which gives me this error in the console:

TypeError: jQuery_1_7_2(...).flexslider is not a function
