All Webroot agent settings can be configured directly from the Webroot Management Console available at: https://my.webrootanywhere.com/default.aspx

Sign into the Webroot Management Console and from the Sites List, locate the key icon for the site you are going to move endpoints to. Click on the key and copy the Keycode.

Then go to the Entities section, click on that site and/or group, and select the devices that will be moved. Once selected, click Agent Commands and choose Change Keycode.

Paste the Keycode you copied and click Send Command. The machines will automatically move to the new site/group.
