In which scenario is it a valid option to transfer a license from one hardware device to another?

Appliance licenses (such as the 4400 series) are hardware-locked and cannot be transferred to an open server platform.

Open server licenses in Check Point are software licenses bound to the open server platform category rather than to a specific hardware vendor, so they can be transferred from an IBM open server to an HP open server. Both devices share the same x86-compatible software environment, making the transfer valid under Check Point's licensing policy.

Licenses cannot be transferred between different Check Point appliance models; appliance licenses are specific to the appliance hardware they were issued for.

Open server licenses cannot be transferred to a hardware appliance such as the 2200 series, as these are separate license categories.
