By performing a warm migration, you migrate a powered on virtual machine from an on-premise vCenter Server to an Org vDC in the cloud.

By performing a warm migration, you create a placeholder VM in the cloud and carry out an initial synchronization between the VM that runs on-premise and the placeholder VM in the cloud.


  • Verify that you have sufficient space available in the target storage profile.

  • You must have a defined Org vDC network.

  • Verify that the VM that you are migrating is powered on.


  1. In the vSphere Web Client, navigate to Home > Inventories > vCloud Director Extender.
  2. In the Migrations tab, click New Migration.
  3. Select Warm migration and click Next.
  4. Select the VM that you want to migrate and click Next.

    When you select a VM, the system verifies if the selected VM is powered on.

    If you select a VM that is powered off, the system returns an error, and you cannot proceed until you select a powered on VM.

  5. Select a Target Cloud, a target vDC, a target storage profile, a target network, and whether you want to group all virtual machines that you are migrating into a single vApp, and click Next.
  6. (Optional) You can initiate the migration at a specific time.
  7. Select a target Recovery Point Objective (RPO).
  8. Select the disk type.
  9. (Optional) Enter a tag for the migration job that you are initiating.
  10. Click Start.


The migration operation is initiated and a new warm migration job appears in the Migrations tab in a Created state.

What to do next

After the warm migration job completes, the warm migration job goes into a cutover-ready status and you can initiate a manual cutover. For more information, see Initiate a Cutover.
