What is the suggested work around for installing ZCM on an OES2 server? They both try to use ports 80 and 443. During the ZCM install it complains about the ports already being in use (I think iManager). I know you can change the ports during the ZCM install, but is there a better alternative? I would really rather not have strange port assignments if possible. Is it best to just set the network card up with two distinct IP addresses and let OES2 have one and ZCM the other one?
