Usage of Obsolete class
<p>We were using class <code>'System.Xml.Xsl.XslTransform'</code> in our project and now recently we started using resharper.  This throw waring Class <code>'System.Xml.Xsl.XslTransform'</code> is obsolete: "This class has been deprecated. Please use <code>System.Xml.Xsl.XslCompiledTransform</code> instead. <a href="http://go.microsoft.com/fwlink/?linkid=14202" rel="nofollow">http://go.microsoft.com/fwlink/?linkid=14202</a>"</p>

<p>Is it good to update the code to new class or keep the existing as the system performs well.</p>

<p>Is there any disadvantages with this approach.</p>
