Change an Application Pool for an Application (IIS 7)


You can assign several applications to the same application pool if all the applications use the same configuration settings. For example, applications that use the same worker process recycling settings or ASP.NET version can run in the same application pool. However, if you have an application that must run with unique settings, you should create a separate application pool for that application.


Exceptions to Feature Requirements

  • None




  3. On the Application Pools page, select the application pool that contains the application that you want to change.

  4. In the Actions pane, click View Applications.

  5. Select the application whose application pool you want to change and then click Change Application Pool in the Actions pane.


To change the application pool in which an application runs, use the following syntax:

appcmd set app /app.name: string /applicationPool: string

The variable app.namestring is the name of the application that you want to change, and the variable applicationPoolstring is the name of the application pool to which you want to add the application. For example, in a site named contoso, to add an application named deals to an application pool named Marketing, type the following at the command prompt, and then press ENTER:

appcmd set app /app.name: contoso/deals /applicationPool: Marketing


The procedure in this topic affects the following configuration elements:

<application> element under <site>



  • Application.ApplicationPool property
