New EULA Licensing - upgrading from EULA to commercial

I am a Chef newbie and I have a question on new Chef licensing model. My understanding is that the newer versions of chef server/client that is downloaded from can be by default be used only for non-commercial purpose (since I accept the license in while I execute chef-server-ctl reconfigure or while using knife bootstrap). After I install, once I get the commercial contract in place, do I need to change anything in my client or do some reconfiguration on server? Any information in this regard would be much appreciated. Thank you
