We have a legacy .Net Application (Asp.net 2.0,.Net Framework 2.0,VS 2005) hosted on IIS6 (windows server 2003) working fine without any issue.Now we want to migrate the application to IIS7 (windows server 2008).I am getting error at Global.asax when I select application pool pipeline mode as "integrated " 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 "classic" and working fine.
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)
Thanks in Advance
