I applied SP15 to Web AS and Portal in my installation, and now I want to deploy the PDK SP14 in portal, but becuase I was using the previous version I need to remove it first till deploy the new one, so for that I'm following the prerequisites of the installation guide, my problem is that I get stuck in the following step, I dont know how to do it. I need you help.
3. Remove the developer content from the content management system.
a. Select Content Management and than Explorer in the top level navigation of the portal.
b. Select Documents in the detail navigation of the portal.
c. Click on the context menu icon right next to the entry DeveloperContent in the content window.
d. Select Delete in the context menu
Thanks in advance
