LIVE DATA CONVERSION AND MIGRATION FOR DISTRIBUTED DATA OBJECT SYSTEMS

Abstract:

Techniques are disclosed for migrating data objects stored by the source DDOS from the source DDOS to the target DDOS while at least the source DDOS is live and available to process requests for access to the data objects being migrated. The techniques also provide eventual consistency between data objects that are created, updated, or deleted in the source DDOS that are applicable to the migration and that occur while the migration is being performed.
