Hi Experts,<br />
<br />
We have &nbsp;a legacy .Net Application (Asp.net 2.0,.Net Framework 2.0,VS 2005) hosted on IIS6 (windows server 2003) &nbsp;working fine without any issue.Now we want to migrate the application to &nbsp;IIS7 (windows server 2008).I am getting error at Global.asax when I select application pool pipeline mode as &quot;integrated &quot;&nbsp;in IIS7 and this error r is due to a design change in the IIS7 Integrated pipeline .I resolved this error just by changing app pool pipeline mode to &quot;classic&quot; and working fine.<br />
<br />
I googled on this issue some recommend &quot;classic&quot; without changing any code and others recommend &quot;Integrate&quot; mode and for this I need to change the code at Global.asax file.<br />
<br />
Can anyone guide me which approach should I opt and what are the implications of using one over &nbsp;the other? (classic vs integrated)<br />
<br />
<br />
Thanks in Advance

Hi Experts,

I googled on this issue some recommend "classic" without changing any code and others recommend "Integrate" mode and for this I need to change the code at Global.asax file.

Can anyone guide me which approach should I opt and what are the implications of using one over  the other? (classic vs integrated)

Migrating from IIS6 to IIS7

IIS is Internet Information Services, the web server included with Windows Server operating systems. All current versions are built on a modular architecture; modules can be added or removed individually so that those required for specific functionality are installed. The full installation of IIS includes HTTP, security, content, compression, caching, logging and diagnostics.

Microsoft IIS Web Server

The successor to Active Server Pages, ASP.NET websites utilize the .NET framework to produce dynamic, data and content-driven web applications and services. ASP.NET code can be written using any .NET supported language. As of 2009, ASP.NET can also apply the Model-View-Controller (MVC) pattern to web applications

ASP.NET

The .NET Framework is not specific to any one programming language; rather, it includes a library of functions that allows developers to rapidly build applications. Several supported languages include C#, VB.NET, C++ or ASP.NET.
