1. Open IIS.
2. Right-click Default Web Site (or name of the website newsite is running under) and select Manage Website > Advanced Settings.
3. Click the Application Pool value and then the  button to select the application pool running New site
4. Click the Physical Path value and then … button to select the directory where the New site application files are located.
5. Click OK.
6. Right-click Default Web Site and select Rename to give it a new name (optional). You may receive an error message saying that ‘Default Web Site’ does not exist. Click OK and then right-click Sites and select Refresh.
7. Expand the website and find the virtual directory for Secret Server.
8. Right-click the virtual directory and select Remove. Click Yes to confirm the operation.
