Service Mode Item Used to Invalidate a License for Transfer to a Different Device (Level 2)
Possible Situation
A license may be used on a different device through transfer, as when replacing the device at the end of a
lease agreement. To do so, the user must first invalidate the existing license by performing a set of steps
referred to as "invalidation of a license" using service mode. At times, both source and target of transfer
may be the same device, and a license therefore may also be invalidated only temporarily. It is important
to note that the user must contact the Sales Company to make a license good regardless of whether it has
been invalidated intentionally or inadvertently.
Invalidation Procedure
Invalidation consists in invalidating the license in service mode and generating an invalidation certificate
that proves the completion of invalidation. Invalidation may take place for individual optional functions,
and a specific function becomes no longer available as soon as an invalidation certificate is issued. The
user contacts the Sales Company and provides the following: the invalidation certificate, the device serial
number of the source of transfer, the device serial number of the target of transfer, reason of transfer. In
response, the Sales Company may issue a license key for new installation on a different device. The user
must take note of the new license key in writing, and keep it as a record after registering it to the target
device.
Installation Procedure
