Need help with HTTPS only and mixed HTTP/HTTPS

You could use an HTTP class or iRule on the existing 10.100.10.10:80 VS which matches on the requested host header value if it equals any of your five domains. The action on the HTTP class or iRule would be to redirect to https://[HTTP::host][HTTP::uri].

Here's an iRule example:

when HTTP_REQUEST {

   switch [string tolower [HTTP::uri]] {
      "www.example.com" -
      "www.example.org" -
      "www.example.net" {
         HTTP::redirect "https://[HTTP::host][HTTP::uri]"
      }
   }
}
