If during the update or upgrade process you are provided with a new serial number, then this update replaces the previous entitlement.
You must delete the previous FlexNet license key from all relevant computers and license servers as a condition of receiving the update or upgrade license. This is because your new license is a replacement seat, not an additional seat, and acquisition of the new license automatically terminates the old one. Use of the old FlexNet license key in that situation is not authorized by Arm® or its licensors. If you instead require an extra seat rather than simply upgrading or updating your existing FlexNet license key to enable the latest version, then you must purchase a new seat license, not an update or upgrade. Quotations for new seats are available on request from Arm or your local Arm authorized reseller.
