VMware assigns a unique UUID to each virtual machine including the VM-Series firewall.So, when a VM-Series firewall is cloned, a new UUID is assigned to it. Because the serial number and license for each instance of the VM-Series firewall is tied to the UUID, cloning a licensed VM-Series firewall will result in a new firewall with an invalid license. You will need a new auth-code to activate the license on the newly deployed firewall. You must apply the capacity auth-code and a new support license in order to obtain full functionality, support, and software upgrades on the VM-Series firewall.
