Migrating services in data communication networks

A network management system for migrating a plurality of communications services in a data communication network, the system comprising:

• at least one processor;
• and
• a memory for storing instructions executable by the at least one processor;
• wherein the at least one processor is configured to:
• access a migration map for the plurality of communications services in the data communication network;
• identify a communications dependency between a first service and a second service in the plurality of communications services according to the migration map, wherein the first service is configured to migrate from a first route to a second route, the second service is configured to migrate from a third route to a fourth route, and the third route overlaps with the second route;
• determine, based on the identified communications dependency, a migration sequence for migrating the plurality of communications services in the data communication network;
• and
• migrate the plurality of communications services from a first plurality of configurations to a second plurality of configurations according to the migration sequence.

A non-transitory computer readable medium storing a set of instructions that is executable by at least one processor of a network management system to cause the network management system to perform operations for migrating a plurality of communications services in a data communication network, the operations comprising:

• accessing a migration map for the plurality of communications services in the data communication network;
• identifying a communications dependency between a first service and a second service in the plurality of communications services according to the migration map, wherein the first service is configured to migrate from a first route to a second route, the second service is configured to migrate from a third route to a fourth route, and the third route overlaps with the second route;
• determining, based on the identified communications dependency, a migration sequence for migrating the plurality of communications services in the data communication network;
• and
• migrating the plurality of communications services from a first plurality of configurations to a second plurality of configurations according to the migration sequence.
