1. An apparatus comprising:

  • a host computer comprising a processor, computer-readable memory and at least one host application;

    a storage array comprising a plurality of computing nodes and persistent storage, each computing node comprising a processor and computer-readable memory, and managing a portion of the persistent storage;

    a cloud gateway comprising a processor, computer-readable memory, and a translation program that translates between a first protocol implemented by the host computer and a second protocol implemented by cloud storage; and

    program code stored on non-transitory computer-readable media that migrates data associated with a logical volume presented to the at least one host application with a first unique device ID between the storage array and the cloud gateway by causing creation of a new logical volume with a second unique device ID that is different than the first unique device ID, causing the data to be written to the new logical volume, and presenting the new logical volume to the at least one host application with the first unique device ID after moving the data, whereby the migration is transparent to the at least one host application.
