When a license management server according to the present exemplary embodiment receives a request for changing a license of a first version to a license of a second version from a license operation server that leases a license to a client, the license management server changes an expiration date of the license of the first version to a predetermined period of time later, and issues the license of the second version. Then, the license of the first version of which expiration date has been changed to the predetermined period of time later and the issued license of the second version are transmitted to the license operation server.
Claims13
A license management server comprising:
- at least a processor and at least a memory coupled to the at least the processor and having stored thereon instructions, when executed by the at least the processor, and cooperating to act as:
- a receiving unit configured to receive a request for upgrading a first license to a second license from a license operation server that leases a license to a client;
- an issuing unit configured to, in a case where the license upgrade request is received, change an expiration date of the first license from indefinite to a predetermined expiration date and issue the second license whose expiration date is indefinite;
- and
- a transmitting unit configured to transmit the first license whose expiration date is the predetermined expiration date and the second license whose expiration date is indefinite,
- wherein, in a case where the receiving unit receives a request for downgrading the second license to the first license from the license operation server,
- the issuing unit changes the expiration date of the second license from indefinite to a predetermined expiration date and issues the first license whose expiration date is indefinite,
- upon receiving the license upgrade request, the issuing unit deletes the first license whose expiration date has been changed to the predetermined expiration date, and
- upon receiving the license downgrade request, the transmitting unit transmits the second license whose expiration date is the predetermined expiration date and the first license whose expiration date is indefinite to the license operation server.
