To move an existing SAP HANA deployment that is currently pinned with Azure NetApp Files to zonal deployment with flexible scale set (FD=1), you must redeploy or migrate the SAP HANA VMs with flexible scale set (FD=1). Additionally, you would need to configure Azure NetApp Files with the [availability zones volume placement feature](../../azure-netapp-files/manage-availability-zone-volume-placement.md) and transfer data to new volumes using backup/restore.

Keep in mind that the availability zone volume placement feature is still in preview.
