We have a McAfee EPO server that has been handling out antivirus solution for the last few years. We are about to shift over to Sophos. I built a virtual machine (Windows 2012r2) to be our new Anti Virus server. I contacted Sophos to assist with the installation but when we went to install the Sophos software we noticed that the McAfee Agent had already been installed on the new server. Sophos insisted I remove it before we continue but when I go to uninstall the agent it tells me that it "Cannot be removed while it is in managed mode". I found my server in the Epolicy Orchestrator 5.1.1 system tree, but do not see how I can make it unmanaged. How can I get this Agent Software off of my new server?
