During the planned failover process, the primary and secondary regions are swapped. The original primary region is demoted and becomes the new secondary region. At the same time, the original secondary region is promoted and becomes the new primary. After the failover completes, users can proceed to access data in the new primary region and administrators can validate their disaster recovery plan. The storage account must be available in both the primary and secondary regions before a planned failover can be initiated.

Microsoft may initiate a regional failover in extreme circumstances, such as a catastrophic disaster that impacts an entire geo region. During these events, no action on your part is required. If your storage account is configured for RA-GRS or RA-GZRS, your applications can read from the secondary region during a Microsoft-managed failover. However, you don't have write access to your storage account until the failover process is complete.

Storage account failovers are a temporary solution which can be used to either help plan and test your DR plans, or to recover from a service outage. Failover shouldn't be used as part of your data migration strategy. For information about how to migrate your storage accounts, see [Azure Storage migration overview](storage-migration-overview.md).

Microsoft provides two REST APIs for working with Azure Storage resources. These APIs form the basis of all actions you can perform against Azure Storage. The Azure Storage REST API enables you to work with data in your storage account, including blob, queue, file, and table data. The Azure Storage resource provider REST API enables you to manage the storage account and related resources.

After a failover is complete, clients can again read and write Azure Storage data in the new primary region. However, the Azure Storage resource provider does not fail over, so resource management operations must still take place in the primary region. If the primary region is unavailable, you will not be able to perform management operations on the storage account.
