Azure Storage Accounts - Switching Replication Types - Tracking Status

Question

How do we track the status of the migration if we are switching a storage account from, say, LRS to GRS ? How long will it take for the replication to complete for existing files and catch up with the latest incoming objects ?

@Chaitanya Cheruvu Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

There is no way to track the progress for LRS è GRS or LRS è ZRS at this moment. There is also no SLA for either of these migrations due to the fact that the timeline for completion is impacted by numerous variables documented here:

 Change how a storage account is replicated - Azure Storage | Microsoft Learn

Azure storage disaster recovery planning and failover - Azure Storage | Microsoft Learn

 GRS replication is asynchronous so technically it may never be in sync directly with incoming writes and the Last Sync Time is reported to users as a result

Additional information:

If customer-initiated conversion could take up to 72 hours to actually begin after you initiate it. There is no SLA for completion of a customer-initiated conversion. For more details about the timing of a customer-initiated conversion, see Timing and frequency.
Customer-initiated conversion is only available from the Azure portal, not from PowerShell or the Azure CLI. To initiate the conversion, perform the same steps used for changing other replication settings in the Azure portal as described in Change the replication setting using the portal, PowerShell, or the CLI.

Customer-initiated conversion is not available in all regions. See the region limitations for more details.

For more information, refer to this article: https://learn.microsoft.com/en-us/azure/storage/common/redundancy-migration?tabs=portal
Note: While Microsoft handles your request for a conversion promptly, there's no guarantee as to when it will complete. If you need your data converted by a certain date, Microsoft recommends that you perform a manual migration instead.

Generally, the more data you have in your account, the longer it takes to replicate that data to other zones in the region.
