NetApp Files How to move volumn from a Premium Qos capacity pool to a Flexible Qos capacity pool

Ming Yan 20

I have a volume in a Premium Qos capacity pool. I just create a new capacity pool with Flexible Qos. I went to the Volume, right click -> Change Pool, the little "Change Pool" panel comes up on the right with a drop down selection for "Pools", however the selection is empty with a message "No Available Items", so I cannot proceed.

Both old and new pool are under the same location, subscription, encryption (single), Qos type (manual), the new pool is current empty (no volume), has sufficient storage capacity and IO throughput. Actually I tried to create a new capacity pool with "Standard" Qos, it does show up in the drop down, so the problem seems to be related to the new Flexible capacity pool option -- I cannot move a volume from a Premium Qos to Flexible Qos, which according to documentation should be allowed. What else am I missing?

Thanks for the answer, which exactly explains what I am seeing.

Currently I have to move the data via snapshot then restore, which involves down time. I guess there is no way to "dynamically" do it now (via CLI etc)?

I think Azure should enhance to allow the volume to be moved from traditional QoS pool to the new Flexible pool.

For now they should also put the limitation to their document on "Dynamically change the service level of an Azure NetApp Files volume", which currently only only states "You can't convert a Flexible service level capacity pool to Standard, Premium, or Ultra. Standard, Premium, and Ultra service level capacity pools can't be converted to the Flexible service level" but not about move a volume to a different pool.

They should also enhance their AI trouble shooter to pick up exactly what you said above.

Hi Ming Yan,

Thanks for posting question in Microsoft Q&A forum,

I have a volume in a Premium Qos capacity pool. I just create a new capacity pool with Flexible Qos. I went to the Volume, right click -> Change Pool, the little "Change Pool" panel comes up on the right with a drop down selection for "Pools", however the selection is empty with a message "No Available Items", so I cannot proceed.

According to this MS-Document [Dynamically change the service level of an Azure NetApp Files volume | Microsoft Learn],

Volumes cannot be directly moved from Premium QoS to Flexible QoS capacity pools in Azure NetApp Files.

Flexible service level pools require manual QoS and cannot accept volumes from Standard, Premium, or Ultra pools, which use auto QoS by default. Documentation explicitly states that Premium (auto QoS) volumes cannot move to Flexible (manual QoS only).

According to this MS-Document [Create a capacity pool for Azure NetApp Files | Microsoft Learn]

The Azure capacity pool creation doc explicitly states that volumes in Flexible service-level capacity pools can’t be moved to another pool, nor can volumes be moved into a Flexible pool:

“Volumes in Flexible service level capacity pools can't be moved to another capacity pool. You also can't move volumes into a Flexible service level capacity pool.”

This is the key block that confirms the behavior you are seeing in the portal, the portal hides pool you cannot move to.

You can move volumes between pools of the same QoS type (e.g., Premium → Standard) using Change Pool.
You cannot move volumes into or out of Flexible service level pools.
Flexible is currently only supported on new manual QoS pools and is a distinct category that doesn’t participate in the normal move workflow

Reference:
Service levels for Azure NetApp Files | Microsoft Learn

Update:

Volumes from Premium QoS pools can't be moved to Flexible ones (portal, CLI like az netappfiles volume pool-change, or API) due to service level mismatch. Snapshot replication to a new volume is the go-to workaround for low downtime.

We'll work on improving the docs and AI troubleshooter to highlight this clearly—your feedback helps a ton. In the meantime, drop suggestions via the Azure Feedback Portal
