Migrate a VM to a Different Disk Tier

To change the disk type for a VM, the virtual datacentre (VDC) must be assigned multiple disk tiers. For example, an 80% reservation pool may have both Tier 1 and Tier 2 disk available.

VM's can be migrated between disk tiers live. Multiple disk tiers can be associated with a single Pool Type.


Follow these steps to migrate a VM to a different disk tier.


1. From the vCloud Director portal, select VDC Virtual Machines tab > Details.



2. The VM details screen will appear. Here you can either:

  • Change the storage policy under General to move all disks to that particular tier, or
  • Under Hard Disks, select the individual policies you need. 



3. Change the Tier as appropriate and click Save. It may take a few minutes for the migration to complete, depending on disk size.


4. To view a list and the details of recent tasks, select Recent Tasks at the bottom left of your screen.



5. The Recent Tasks list appears showing the details of VM activity. Select a task to view the details. 



6.  The Task Details screen appears. Click OK to when you have finished viewing.
