Abstract
An instruction is received to migrate a first storage unit at a first appliance to a second appliance, the instruction being received while receiving file IO associated with ingesting files from a client-side deduplication library into the first storage unit. Synchronization of a second storage unit at the second appliance with the first storage unit is started. Upon reaching a threshold level of synchronization, the client-side library is notified of the migration. The threshold level is less than a complete synchronization. The client-side deduplication library closes currently open files to flush pending data to the first storage unit and suspends file IO. After the suspension, the synchronization is completed and the client-side library is notified of the completion. The client-side library reopens the closed files to resume the file IO of the now opened files to the second storage unit.
