I'm still trying to get my head around the back end of the new licensing. I'm upgrading about 500 LWFs to 4.2.1. I see how I can convert over to a forwarder license in the GUI, but I'm not sure what changes in the background. Is there a file I'm missing or can this be done via the CLI? I'm not finding anything in the docs so far. I see some mention of forwarder licensing in the Universal Forwarder, but it was confusing.
