Will that cause the core count config to change or is the license core count config changed only done on reboot?<BR />2. If you cpstop and cpstart after removing the license, would that also cause the fw workers to change (without rebooting) before adding it back?</P><P>I know that if you detatch a central license, you get a warning that the core count will change because of licensing if you remove a license.&nbsp; Is there some mechanism that gets triggered that forces that even if you add a license back before rebooting?<BR /><BR />I am just wanting to understand this behavior as it would be useful to know for upgrades.</P> Fri, 28 Feb 2025 22:01:27 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Detach-license-and-then-add-it-back-later-Does-core-config/m-p/242726#M47169 Adam276 2025-02-28T22:01:27Z https://community.checkpoint.com/t5/Firewall-and-Security-Management/Detach-license-and-then-add-it-back-later-Does-core-config/m-p/242835#M47191 <P>You should get a message about changing the core count when the license is removed.<BR />This is something I see regularly applying an "all-in-one" eval license to my standalone gateway (specifically overwriting the old license).</P> <P>However, I don't think it changes the actual core count running until a reboot or cprestart.<BR />Having said that, I haven't tried passing traffic in this state where I haven't applied the gateway portion of the All-in-One license yet.<BR /><BR /></P> Mon, 03 Mar 2025 16:23:09 GMT https://community.checkpoint.com/t5/Firewall-and-Security-Management/Detach-license-and-then-add-it-back-later-Does-core-config/m-p/242835#M47191 PhoneBoy 2025-03-03T16:23:09Z
