Automated migration of virtual volumes between storage virtualization appliances

A computer program product comprising a non-transitory processor-readable storage medium having stored therein program code of one or more software programs, wherein the program code when executed by at least one processing device causes the at least one processing device:

• to select, from a first storage virtualization appliance, one or more virtual volumes to migrate to a second storage virtualization appliance;
• to determine a configuration of a first set of storage elements of the first storage virtualization appliance utilized to implement the selected one or more virtual volumes;
• to provision a second set of storage elements for implementing the selected one or more virtual volumes on the second storage virtualization appliance, the second set of storage elements being provisioned in an inactive state;
• to pause input-output operations directed to the selected one or more virtual volumes on the first set of storage elements of the first storage virtualization appliance;
• to modify (i) the first set of storage elements of the first storage virtualization appliance from an active state to the inactive state and (ii) the second set of storage elements of the second storage virtualization appliance from the inactive state to the active state;
• and
• to resume input-output operations directed to the selected one or more virtual volumes on the second set of storage elements of the second storage virtualization appliance.

A method comprising:

• selecting, from a first storage virtualization appliance, one or more virtual volumes to migrate to a second storage virtualization appliance;
• determining a configuration of a first set of storage elements of the first storage virtualization appliance utilized to implement the selected one or more virtual volumes;
• provisioning a second set of storage elements for implementing the selected one or more virtual volumes on the second storage virtualization appliance, the second set of storage elements being provisioned in an inactive state;
• pausing input-output operations directed to the selected one or more virtual volumes on the first set of storage elements of the first storage virtualization appliance;
• modifying (i) the first set of storage elements of the first storage virtualization appliance from an active state to the inactive state and (ii) the second set of storage elements of the second storage virtualization appliance from the inactive state to the active state;
• and
• resuming input-output operations directed to the selected one or more virtual volumes on the second set of storage elements of the second storage virtualization appliance;
• wherein the method is performed by at least one processing device comprising a processor coupled to a memory.
