A method and system for transferring licenses between electronic devices supporting licensable features. Specifically, in a method a request is generated for transferring a license between first and second electronic devices. The request includes first information unique to the first electronic device, second information unique to the second electronic device. The request is sent to a license distributor to generates a master key. The master key includes a removal key including the first information and an add key including the second information. The removal key is used to remove the license from the first electronic device when the first information matches official versions of the first information. The add key is revealed from the master key when the license is successfully removed. The add key is used to add the license to the second electronic device when the second information matches official versions of the second information.

1. A system comprising: a computer processor;a memory connected to the computer processor, the memory storing instructions that, when executed, cause the computer processor to perform the steps of:receiving a request to transfer a license for a service feature from a first network device to a second network device, wherein the request identifies the first network device, the second network device and a description of the license to be transferred;generating a master key in response to the received request, which effects a transfer of the license, wherein the master key includes a removal key and an add key;installing the master key at the first network device;removing the license from the first network device based on the removal key;extracting the add key from the master key in response to the removing of the license; andadding the license to the second network device based on the add key. 2. The system of claim 1, wherein the memory stores further instructions that, when executed, cause the computer processor to perform the step of: encrypting the master key. 3. The system of claim 1, wherein the add key is used to add the license to the second network device after the license is removed from the first network device based on the removal key. 4. The system of claim 1, wherein the memory stores further instructions that, when executed, cause the computer processor to perform the steps of: formatting the removal key according to a first software version operating on the first network device, and formatting the add key according to a second software version operating on the second network device. 5. The system of claim 4, wherein the request identifies the first software version operating on the first network device and the second software version operating on the second network device. 6. The system of claim 1, wherein the memory stores further instructions that, when executed, cause the computer processor to perform the step of: transmitting the master key towards the first network device and the second network device. 7. The system of claim 1, wherein the description of the license includes at least one of: a number of licenses to be transferred and a type of the license. 8. The system of claim 1, wherein the master key further includes at least one of: a number of licenses to be transferred, a type of the license, a network device identifier, and a network device sequence number. 9. The system of claim 1, wherein the removal key includes at least one of: an identifier associated with the first network device, a sequence number associated with the first network device, and a software version associated with first network device. 10. The system of claim 1, wherein the add key includes at least one of: an identifier associated with the second network device, a sequence number associated with the second network device, and a software version associated with second network device. 11. The system of claim 1, wherein the memory stores further instructions that, when executed, cause the computer processor to perform the step of: receiving the request from a user. 12. The system of claim 6, wherein the memory stores further instructions that, when executed, cause the computer processor to perform the step of: transmitting the master key to a user before the master key reaches the first network device or the second network device.
