Migrate vVol-based VMs to another appliance

Use this feature to migrate vVol VMs to another appliance in the cluster without any disruption to host I/O.

About this task

When you migrate a vVol-based VM, all associated fast clones and snapshots also migrate with the storage resource. During the migration, additional work space is allocated on the source appliance to facilitate data movement. The amount of space that is needed depends on the number of storage objects and amount of data being migrated. This work space is released and freed up after the migration is complete.

NOTE:Only vVol-based VMs can be migrated. Migrating VMFS-based VMs is not supported.


  1. Under Compute, select Virtual Machines.
  2. Select the vVol-based VM to migrate, then select More Actions > Migrate.
    The Migrate slide-out panel is displayed. The system will run checks to ensure the VM is applicable for migration.
    NOTE:If the VM is protected, the entire VM replication group will be migrated.
  3. Select the Destination Appliance for the VM migration.
  4. Select Start Migration Immediately to migrate now, or Defer Migration to perform the migration at a later time.
    When selecting Defer Migration, the migrations session is created, but not started. It can be started at a later time from the Migration page.
