 Zone-redundant registries can be deployed into [any region that supports availability zones](./regions-list.md).
 
+If your registry is in a region that doesn't support availability zones, then to make it zone-redundant you must create a new registry in a region that supports availability zones. Then, you need to migrate your container images by [creating a transfer pipeline](/azure/container-registry/container-registry-transfer-prerequisites) or by [importing container images](/azure/container-registry/container-registry-import-images).

 ### Considerations
 
-Container Registry tasks don't currently support availability zones. Zone redundancy applies to the registry service itself, but not to tasks or their operations.
+- **Tasks:** Container Registry tasks don't currently support availability zones. Zone redundancy applies to the registry service itself, but not to tasks or their operations.

+- **Geo-replication:** If your registry uses [geo-replication](#multi-region-support), any replicas created in regions with availability zones are made zone-redundant automatically.
 
 ### Cost
 
 Zone redundancy is included with container registries at no extra cost.
