Online cross-pool data migration method and electronic equipment

The invention relates to the technical field of data migration, in particular to an online cross-pool data migration method and electronic device.According to the online cross-pool data migration method, a central controller is responsible for generating monotonically increasing natural numbers, and a tree structure is used for managing the relation between storage pools and volumes on a global configuration server, so that when volumes are migrated between the different storage pools, the volume migration speed is improved, and the volume migration efficiency is improved. The method comprises the following steps of: removing the mapping of the volume from a source storage pool, remapping the volume into a target storage pool, and finally exporting the volume from different storage pools through the same Target so as to finish distributed data migration on line asynchronously. According to the method, the globally unique volume ID is adopted, the relation between the volume and the storage pool and export of
