14 results about "Object migration" patented technology

Techniques are provided for migrating a volume utilizing an object copy work queue and an object copy driver module. Data of the volume is stored within objects stored across a storage tier and capacity tier of a source object store. As part of migrating the volume to a destination object store, the objects are migrated to the destination cluster. Directly copying the objects involves multiple read operations to the source object store and a write operation at the destination object store. The techniques provided herein improve the efficiency of the migration by initially sending metadata from the source object store to the destination object store for performing backend object copy operations to migrate the volume. This results in fewer operations and less network usage, thus improving the efficiency and cost of migrating the volume.

The isomer database data migration method relates to the technical field of data migration, and automatically judges the source database type by analyzing the meta information in the source database collection package. Then, the SQL of the source database is subjected to lexical and syntactic analysis to form a syntax tree object of the source database. The syntax tree object of the source database and the target database syntax tree object are subjected to object migration and conversion to complete the mapping of the syntax tree object. The target syntax tree object is converted into a target database object script through rule conversion and rewriting conditions, and automatic data migration is realized.
