Registering source clusters

To migrate from CDH to Cloudera on cloud, you need to register the CDH or Cloudera Base on premises cluster as a source from which the data, metadata and workload will be migrated.

Make a note of the following information about the CDH cluster to complete the source registration:
  • Cloudera Manager URL
  • Admin username and password for Cloudera Manager
  • SSH user, port, and private key
  1. Click See More > Register A New Source on the homepage of Cloudera Migration Assistant to register a cluster that will be used as a source for the migration.

    Alternatively, you can open the New Cluster wizard by selecting Clusters on the left navigation pane, and clicking New > Source.

  2. Select Cloudera Distributed Hadoop 5, Cloudera Distributed Hadoop 6 or Cloudera Base on premises as Source Type.
  3. Provide the URL of Cloudera Manager that belongs to the CDH 5, CDH 6 or Cloudera Base on premises cluster.
    The URL needs to be in the following format:
    https://[***CLOUDERA MANAGER HOSTNAME***]:[***CLOUDERA MANAGER PORT***]/
  4. Provide the Admin user and Admin password of Cloudera Manager.
  5. Click Next.
  6. Choose the cluster based on the Cluster Name that you want to use for the migration.
    The drop-down list contains all of the clusters that are managed by Cloudera Manager on the provided host.
  7. Click Next.
  8. Select the Configuration Preference based on which authentication method you prefer.
    • Choose Use existing if you want to use the SSH configuration and keys of the user running Cloudera Migration Assistant server to access the hosts.
    • Choose New if you want to use a newly provided SSH key to configure Ansible automatically.
      1. Provide the SSH User and SSH Port.
      2. Copy the SSH Key to the SSH Key box or upload a .pem file containing the key.
      3. If you want to use Password, provide the password and make sure the sshpass utility is installed.
  9. Click Create.
The registered CDH or Cloudera Base on premises cluster is listed on the Clusters page.
You can review the details and services of the cluster by clicking on the Name of the cluster.
Scan the data and workloads on the registered source cluster and add labels to specify the objects, which should be included in the migration.
