Resolving Load balancer Plug-in Problems During Side-by-Side Upgrade

While upgrading from Application Server 7.1 EE to Application Server 8.2 EE, during a side-by-side upgrade, you will not be able to point your new 8.2 load balancer plug-in to the old 7.1 web server installation, if the load balancer plug-in is colocated with other Application server components on a single system. You need to install web server again and point the 8.2 load balancer plug-in installation to the instance belonging to the new installation.
