Explanation

The SAP software license is tied to a hardware key. SAP Kernel 7.49 and below derives the hardware key from underlying physical hardware identifiers, which differ between Xen-based virtualization (used by older instance types like m4) and KVM-based virtualization (used by newer instance types like m5). When the instance type changed from m4.large (Xen) to m5.xlarge (KVM), the hardware key changed, invalidating the existing license and triggering the expiration warning. Newer SAP kernel patch levels generate the hardware key using the instance UUID, which remains stable across virtualization platform changes. The fix is to upgrade the SAP kernel to a version that uses the instance UUID-based hardware key, then request a new license from SAP.
