 <sup>2</sup> Migrating from LRS to GRS is not supported if the storage account contains blobs in the archive tier.<br />
 <sup>3</sup> Live migration is supported for standard general-purpose v2 and premium file share storage accounts. Live migration is not supported for premium block blob or page blob storage accounts.<br />
 <sup>4</sup> After an account failover to the secondary region, it's possible to initiate a fail back from the new primary back to the new secondary with PowerShell or Azure CLI (version 2.30.0 or later). For more information, see [Use caution when failing back to the original primary](storage-disaster-recovery-guidance.md#use-caution-when-failing-back-to-the-original-primary). <br />

 > [!CAUTION]
 > If you performed an [account failover](storage-disaster-recovery-guidance.md) for your (RA-)GRS or (RA-)GZRS account, the account is locally redundant (LRS) in the new primary region after the failover. Live migration to ZRS or GZRS for an LRS account resulting from a failover is not supported. This is true even in the case of so-called failback operations. For example, if you perform an account failover from RA-GZRS to the LRS in the secondary region, and then configure it again to RA-GRS and perform another account failover to the original primary region, you can't contact support for the original live migration to RA-GZRS in the primary region. Instead, you'll need to perform a manual migration to ZRS or GZRS.
