Techniques are described for merging device schemas to manage different versions of network devices in the same device family. In one example, a computing device includes an interface to receive a first schema to be used for managing a first version of a device in a device family and a second, different schema to be used for managing a second version of the device, a computer-readable medium encoded with instructions for a schema merger module, and a processor to execute the schema merger module to merge the first schema and the second schema to produce a resulting merged schema to be used for managing both the first version of the device and the second version of the device, wherein the resulting merged schema expresses differences between the first schema and the second schema and includes a single instance of each common portion between the first schema and the second schema.

Merging network device configuration schemas

A database enables versioning for objects stored in the database via a 'snapshot' operation. In one implementation, a device performs a snapshot operation in which a snapshot object, representing a logical view of database objects at a time at which the snapshot operation is performed, is created and stored in the database. In response to a request to store a modified version of a database object, the modified version of the database object is written to replace the previous version of the database object when the database object was last modified after the most recent snapshot operation. Further, in response to the request to store the modified version of the database object, the modified version of the database object is inserted in the database when the previous version of the database object was last modified before the most recent snapshot operation.
