solution that woked for me . Check the web.config file after u run this you can see the change

You could see the handlers & modules moved to 
    system.webServer

%SystemRoot%\system32\inetsrv\appcmd migrate config "Default Web Site/". 

%SystemRoot%\system32\inetsrv\appcmd migrate config "Your Subdomain name or website name or virtual directory/".

Most likely causes: 
This application defines configuration in the system.web/httpModules section. 
Things you can try:

Migrate the configuration to the system.webServer/modules section. You can do so manually or by using AppCmd from the command line - for example, %SystemRoot%\system32\inetsrv\appcmd migrate config "Default Web Site/". Using AppCmd to migrate your application will enable it to work in Integrated mode, and continue to work in Classic mode and on previous versions of IIS. 
If you are certain that it is OK to ignore this error, it can be disabled by setting system.webServer/validation@validateIntegratedModeConfiguration to false. 
Alternatively, switch the application to a Classic mode application pool - for example, %SystemRoot%\system32\inetsrv\appcmd set app "Default Web Site/" /applicationPool:"Classic .NET AppPool". Only do this if you are unable to migrate your application. 
(Set "Default Web Site" and "Classic .NET AppPool" to your application path and application pool name)
