Support for changing storage type when VM is powered down in Azure

With this feature, in Azure environments, you now have an option to change the storage type to a lower tier at shutdown and restore the storage tier when the VM is powered on. This saves on storage cost while the VM is shut down. The storage performance might also be impacted at start time. For persistent VMs, the OS disk is changed to the selected storage type at shutdown and restored to the defined storage type at power on. For non-persistent VMs, if MCSIO is enabled and persistence is selected, OS disk and WBC disk are changed to the selected storage type at shutdown and restored to the defined storage type at power on.
