jquery更新后怎样在一个站点中使用两个版本号的jQuery

公司眼下的项目中的右側导航菜单用到了bootstrap(v3.2.0)的affix.js(Affix插件)与scrospy.js(滚动监听)插件，须要用到版本号>= 1.9.0的jquery,眼下最新的jquery版本号是2.1.1。公司之前用的jquery版本号是1.6.2的，怎样在同一个站点里应用不同版本号的jquery而不引起冲突呢？在网上查了资料找到可解决的方法。

<script type="text/javascript" language="javascript" src="jquery-1.6.2.min.js"></script>


<script type="text/javascript" language="javascript" src="jquery-2.1.1.min.js"></script>
<script type="text/javascript">var jQuery_211 = $.noConflict(true);</script>

// 分别改动affix.js和scrospy.js中的$或jQuery为jQuery_211
