Control Manager can manage products regardless of physical location and so it is possible to manage all your antivirus and content security products using a single Control Manager server.
Since Control Manager supports multiple user accounts, segregation that was necessary for Trend Virus Control System (Trend VCS) is no longer necessary. For information about upgrading Trend VCS servers, see Upgrading Trend VCS 1.8x servers.
However, there are advantages to dividing control of your Control Manager network among different servers (including parent and child servers for Enterprise Edition users). Based on the uniqueness of your network, you can decide the optimum number of Control Manager servers.
