 This feature was introduced in [v1.1.1](https://github.com/dgraph-io/dgraph/releases/tag/v1.1.1).
 For migrating unencrypted data to a new Dgraph cluster with encryption enabled, you need to

 You can import data on a running Dgraph instance (which may have prior data) using Dgraph CLI command [dgraph live]({{< relref "cli/live.md" >}}) referred to as **Live Loader**.
 Live Loader sends mutations to a Dgraph cluster and has options to handle unique IDs assignment and to update existing data.

 Verify that you have a local folder `<local-path-to-data>` containing
 - at least one **data file** in RDF or JSON in plain or gzip format with the data to import
 - an optional **schema file**.
