Abstract

A network device management may cause initiation of an in-service software upgrade (ISSU) procedure that is associated with an updated state schema and may cause, based on causing the ISSU procedure to be initiated, generation of a current state snapshot of a distributed data store (DDS) that is associated with a current state schema. The network device management may obtain the current state snapshot and may identify one or more objects that conform to the current state schema in the current state snapshot. The network device management system may cause transformation of the one or more objects that conform to the current state schema into one or more objects that conform to the updated state schema and may cause generation of an updated state snapshot associated with the updated state schema. The network device management system may cause an update of the DDS based on the updated state snapshot.

Dependent claims

A method, comprising:

causing, by a network device management system using an update utility, initiation of an in-service software upgrade (ISSU) procedure that is associated with an updated state schema;
causing, by the network device management system using the update utility and based on causing the ISSU procedure to be initiated, generation of a current state snapshot of a distributed data store (DDS) that is associated with a current state schema;
obtaining, by the network device management system using a transformer utility, the current state snapshot;
identifying, by the network device management system using the transformer utility, one or more objects that conform to the current state schema in the current state snapshot;
causing, by the network device management system using the transformer utility, transformation of the one or more objects that conform to the current state schema into one or more objects that conform to the updated state schema;
causing, by the network device management system using the transformer utility and based on the one or more objects that conform to the updated state schema, generation of an updated state snapshot associated with the updated state schema;
and
causing, by the network device management system using the update utility, an update of the DDS based on the updated state snapshot.

5 more elements

A non-transitory computer-readable medium storing a set of instructions, the set of instructions comprising:

one or more instructions that, when executed by one or more processors of a network device management system, cause the network device management system to:
obtain, in association with an in-service software upgrade (ISSU) procedure that is associated with an updated state schema, a current state snapshot of a distributed data store (DDS) that is associated with a current state schema;
identify one or more objects that conform to the current state schema in the current state snapshot;
identify information that indicates one or more transformation differences between the current state schema and the updated state schema;
cause, based on the information, transformation of the one or more objects that conform to the current state schema into one or more objects that conform to the updated state schema;
and
cause, based on the one or more objects that conform to the updated state schema, generation of an updated state snapshot associated with the updated state schema.

4 more elements

A network device management system, comprising:

one or more memories;
and
one or more processors to:
obtain, in association with an in-service software upgrade (ISSU) procedure that is associated with an updated state schema, a current state snapshot that is associated with a current state schema;
identify one or more objects that conform to the current state schema in the current state snapshot;
identify information that indicates one or more transformation differences between the current state schema and the updated state schema;
cause, based on the information, transformation of one or more objects that conform to the current state schema and that are in the current state snapshot into one or more objects that conform to the updated state schema;
and
cause, based on the one or more objects that conform to the updated state schema, generation of an updated state snapshot associated with the updated state schema.
