After an account failover to the secondary region, it's possible to initiate a failback from the new primary back to the new secondary with PowerShell or Azure CLI (version 2.30.0 or later). [Initiate the failover](storage-initiate-account-failover.md#initiate-the-failover).

If you performed a customer-managed account failover to recover from an outage for your GRS account, the account becomes locally redundant (LRS) in the new primary region after the failover. Conversion to ZRS or GZRS for an LRS account resulting from a failover isn't supported, even for so-called failback operations. For example, if you perform an account failover from GRS to LRS in the secondary region, and then configure it again as GRS, it remains LRS in the new secondary region (the original primary). If you then perform another account failover to failback to the original primary region, it remains LRS again in the original primary. In this case, you can't perform a conversion to ZRS or GZRS in the primary region. Instead, perform a manual migration to add zone-redundancy.

After a zone-redundancy conversion, you must wait at least 72 hours before changing the redundancy setting of the storage account again. The temporary hold allows background processes to complete before making another change, ensuring the consistency and integrity of the account. For example, going from LRS to GZRS is a 2-step process. You must add zone redundancy in one operation, then add geo-redundancy in a second. After going from LRS to ZRS, you must wait at least 72 hours before going from ZRS to GZRS.
