    Before you migrate your applications to the Data Fabric Hadoop distribution, consider testing your applications using a small subset of data.
  - Data Migration
    After you migrate your applications to the Data Fabric cluster, you can copy your data from the Apache Hadoop HDFS to the Data Fabric cluster.
    - Using the hdfs:// Protocol
      This section describes how to copy data from an HDFS cluster to a MapR cluster using the hdfs:// protocol.
    - Using the webhdfs:// Protocol
      This section describes how to copy data from an HDFS cluster to a Data Fabric cluster using the webhdfs:// protocol.
    - Using NFS
      This section describes how to copy data from an HDFS cluster to a Data Fabric cluster using NFS.
  - Node Migration
    You can add decommissioned HDFS data nodes to your HPE Ezmeral Data Fabric cluster.
- Applying a Patch
  You can apply a patch by using the Installer, by using the command line (a manual process), or by using an Installer Stanza.

Data Migration

After you migrate your applications to the Data Fabric cluster, you can copy your data from the Apache Hadoop HDFS to the Data Fabric cluster.

Once you have installed and configured your Data Fabric cluster in a test environment and migrated your applications to the Data Fabric cluster you can begin to copy over your data from the Apache Hadoop HDFS to the Data Fabric cluster.

Use any of the following methods to copy data from an HDFS cluster to a Data Fabric cluster:

Method	Description
hdfs:// protocol	You can use the hadoop distcp command with the `hdfs://` protocol to copy data from an HDFS cluster into a Data Fabric cluster. Use this method if the HDFS cluster and the Data Fabric cluster use the same RPC protocol version. For all other scenarios, use the `webhdfs://` protocol or NFS gateway to copy data to a Data Fabric cluster.
webhdfs:// protocol	You can use the hadoop distcp command with the `webhdfs://` protocol to copy data from an HDFS cluster into a Data Fabric cluster.
NFS	You can mount a Data Fabric cluster to an HDFS cluster via NFS mount and then use the hadoop distcp command to copy data between the two clusters.
