You can make use of coditional comments and javascript to do that.
Something like following should work-
<!doctype html>
<!--
<!-- <html class=""> <!--
<head>
Javascript:
(function ($) {
"use strict";
if ($('html').is('not_supported')) {
alert("This browser version is not supported");
window.location.href = 'http://www.google.com';
}
}(jQuery));
Hope, it helps :)
Let me know if it doesn't work.
