One or more servers may receive an instruction to change a modulation format, associated with one or more optical channels, from a first modulation format to a second modulation format; provide the instruction to change the modulation format to a network device, associated with the one or more optical channels, to cause the network device to change the modulation format, associated with the one or more optical channels, from the first modulation format to the second modulation format; and determine that a license repository is to be updated based on receiving the instruction to change the modulation format. The license repository may store one or more licenses. The one or more servers may generate a license update instruction to update the license repository based on determining that the license repository is to be updated and output the license update instruction to cause the license repository to be updated.
