There should be 2 good ways to do this.
I usually just grab the config files (*.cfg) of probes that I want to relocate and copy them to the new server. That is very simple, but it only works well when you can easily get a file from one server to another.
There is also a fairly easy way to do the same thing in the NimBUS Manager. You should be able to drag and drop the probe from the old hub back onto your Archive. When prompted, change the probe name to something like net_connect_config. Then install the real net_connect probe to the new hub. After it is installed, drag and drop your new net_connect_config package onto the new hub. This will update the configuration settings on the new hub to match those on the old hub.
There is very little magic about the NimBUS Manager option. You can open your net_connect_config package and check out the net_connect.cfx file that it contains. That is the file that ends up updating the config on your new hub.
Let us know how it goes.
