I am trying to do an upgrade from 126.96.36.199 to 188.8.131.52 but release notes say to upgrade to 184.108.40.206 first, since users, etc. wont migrate. My question is: when I go through the install, it tells me I have WCS already installed. I say of and continue, it then says it's using port 80 and I should change this to go forward. Well, I am just trying to upgrade and not install another WCS on the server. Is there a process I am missing?
