Not able to change the redundancy of storage account from LRS to RA-GRS

Hi @Mansi Awasthi ,

please take a look here how to change the redundancy of an Azure Storage account: Customer-initiated conversion

The status of the conversion can be monitored as well: Monitoring customer-initiated conversion progress

If you get an error message if you try to convert the redundancy of the Azure Storage Account it would be helpful to see the error message details.

Yes I am getting this error message when I am trying to change the redundancy from LRS to GRS or RA-GRS

Failed to update redundancy for storage account 'ocdmrevprd01pvtvty5kevxe'. Error: Sku update from Standard_LRS to Standard_RAGRS is not allowed at the moment. Please try again later.

Hi @Mansi Awasthi ,

this error message could show up if there are maintenance or data sync tasks are running in the affected region.

The only option if so is to wait an retry again.

Here you can verify if there are planned maintenance tasks: Service Health | Planned maintenance

Or if there were tasks in the history: Service Health | Health history

hello Mansi Awasthi

We looked into the error encountered when trying to switch the storage account redundancy from LRS (Locally Redundant Storage) to RA-GRS (Read-Access Geo-Redundant Storage):

"Failed to update redundancy for storage account 'ocdmrevprd01pvtvty5kevxe'. Error: Sku update from Standard_LRS to Standard_RAGRS is not allowed at the moment. Please try again later."

Microsoft guidance indicates that changing redundancy from LRS to RA-GRS is supported for Azure Storage accounts. That said, this error usually means Azure is temporarily blocking the SKU conversion because of a service-side restriction, an unsupported configuration, or data/features that can interfere with redundancy changes.

To investigate further, please share the following details:

• Storage account region
• Storage account type (StorageV2, BlobStorage, GPv1, etc.)
• Whether Hierarchical Namespace (ADLS Gen2) is enabled
• Approximate storage account data size
• Confirmation whether any blobs, blob versions, snapshots, or soft-deleted blobs are currently in the Archive tier

Archived blobs, archived versions, archived snapshots, or soft-deleted archived data may block redundancy changes and might need to be rehydrated before the operation can continue.Please check the reference documents:
