Abstract
Embodiments of the disclosure provide a method, a computer [program product and apparatus for a soft-switch in a storage system, by setting data in a source of the soft-switch to be read-only and starting a replication process of the data to a destination of the soft-switch in response to a soft-switch request; recording at the source an update operation for the data during the replication process and synchronously recording the update operation into the destination; updating the replicated data at the destination with the synchronously recorded update operation in response to the completion of the replication process; and disabling a data access to the source and enabling a data access to the destination.
