I have existing eSRS GW but planned to deploy SCG instead of upgrade.  I just deploy the SCG Policy Manager and will get all the new port opened.  My plan is to shutdown eSRS GW and deploy SCG GW with same IP as SCG GW.  So, I don't need to go thru to pain to open ports again.  Only question is the port requirement.  I only use it to monitor Isilon, DD, VMAX and PowerMAX and have no plan to monitor any other devices.  From the upgrade from eSRS to SCG guide, only new ports required are 8443/443 from GW to esrs3-core.emc.com and esrs3-coredr.emc.om as well as 5700 for the web client.    However, from the SCG deployment guide, I see a lot of new requirements.  Are they really required in my case?  I don't use it to monitor Dell servers etc.  They are handled by server team.
