This article describes how to change the IP addresses of your Windows Essential Business Server (EBS) computers. You can use the Change IP Address Settings Wizard to change the IP address settings of a network adapter on the Windows EBS Management Server, Security Server, or Messaging Server. When you change the IP address settings on one server, the wizard reconfigures connections to the other two servers to keep your network functioning properly. For more information on all the settings that are changed please see http://technet.microsoft.com/en-us/library/d37f87de-5601-4a9f-9487-a79779933100.

This is all fine, but it's not very pretty if you decide to put the security server in another subnet and using your guidelines.
Basically your telling the users to add a static routes to be able reach the security server, which is the gateway for messaging and management.
Hovewer, if you already have to subnets, chances are that you also have routing capabilities between them.
You solution bypasses this might not be optimal.
To do this properly one would after the move of the security server add a route on the messaging and management server to the securityserver, I wouldn't make it persistent, specifying which gateway on the local subnet to use to reach the securityserver. Then you could run the tool on both server changing to the correct gateway ip and then reboot both server to loose the routes, or route delete them.
I think the tool could be wastly improved if you get an option to specify a new gateway for messaging and management when moving the securityserver out of the subnet.
