Gheist, first of all sorry for not coming back to you on the earlier question "http://www.experts-exchange.com/Operating_Systems/FreeBSD/Q_21791768.html
" asked as I couldn't carry out the activity until recently for the fear of bringing down the Live Server. Anyway, I must say the upgrade went on flawlessly, thanks to you.
I was able to install BSNMP as suggesed using ports, but when the command to start the Service is executed, it only gives a message saying "Starting bsnmp" and returns the Prompt. When I check the running processes, I see no snmp service running. The ManageEngine still reports the same error.
I've also made the necessary changes in the rc.conf to start service on startup, but even after the system is rebooted, I do not find the smpt service running.
