+## Live migration to ZRS FAQ
+
+**Should I plan for any downtime during the migration?**
+
+There is no downtime caused by the migration. During a live migration, you can use your storage account while your data is migrated between source and destination storage stamps. During the migration process, you have the same level of durability and availability SLA as you normally do.
+
+**Is there any data loss associated with the migration?**
+
+There is no data loss associated with the migration. During the migration process, you have the same level of durability and availability SLA as you normally do.
+
+**Are any updates required to the application(s) once the migration is complete?**
+
+Once the migration is complete the replication type of the account(s) will change to "Zone-redundant storage (ZRS)". Service endpoints, access keys, SAS and any other account configuration options remain unchanged and intact.
+
+**Can I request a live migration of my general-purpose v1 account(s) to ZRS?**
+
+ZRS only supports general-purpose v2 accounts so before submitting a request for a live migration to ZRS make sure to upgrade your account(s) to general-purpose v2. See [Azure storage account overview](https://docs.microsoft.com/azure/storage/common/storage-account-overview) and [Upgrade to a general-purpose v2 storage account](https://docs.microsoft.com/azure/storage/common/storage-account-upgrade) for more details.
+
+**Can I request a live migration of my read-access geo-redundant storage (RA-GRS) account(s) to ZRS?**
+
+Before submitting a request for a live migration to ZRS make sure your application(s) or workload(s) no longer require access to the secondary read-only endpoint and change the replication type of your storage account(s) to geo-redundant storage (GRS). See [Changing replication strategy](https://docs.microsoft.com/azure/storage/common/storage-redundancy#changing-replication-strategy) for more details.
+
+**Can I request a live migration of my storage account(s) to ZRS  to another region?**
+
+You can only migrate data within the same region. If you want to migrate your data into a ZRS account located in a region different than the source account, then you must perform a manual migration.
