CDP Upgrade and Migrations Paths

Take a look at the overview, features, and advantages of CDP and know the upgrade and migration paths from CDH or HDP platform to CDP.

Introduction to CDP

The merger of Cloudera and Hortonworks led to the new Cloudera Data Platform or CDP, which is the combined best of breed Big Data components from both Cloudera and Hortonworks.

Review the following information before you upgrade or migrate to Cloudera Data Platform (CDP):
  • CDP Overview
  • CDP Private Cloud Base new features

Troubleshooting

A selection of Cloudera Knowledge Base articles are available that describe common issues encountered by Cloudera customers during upgrades and migrations. See CDP Upgrade/Migrate Troubleshooting Articles. (Cloudera login required.)

CDP upgrade and migration paths are:

CDP Upgrade and Migration Paths for Data-at-Rest

If you are an HDP or a CDH user, you can follow one of the several upgrade or migration paths to CDP.

Migration and Upgrade Paths Description
In-place upgrade Recommended for large clusters. Other paths are not viable. Involves downtime. See the following to know more about the In-place upgrade paths:
Migrate to new cluster Recommended if you are ready for a hardware refresh or have small clusters. You can fall back to your original cluster in the event of upgrade issues. Requires additional hardware.
Direct to cloud migration Recommended if you can tolerate some cluster downtime or have bursty workloads. See the following to know more about the direct to cloud migration paths:
  • Nifi workloads

    If you are running NiFi workloads without Hive, Impala, HBase, or Kafka: Migrate to CDP Data Hub and use the Flow Management cluster template.

  • Kafka workloads

    If you are running Kafka workloads without Hive, Impala, HBase, or NiFi: Migrate to CDP Data Hub and use the Streams Messaging cluster template.

  • HBase workloads

    If you are running HBase workloads without Hive or Impala: Migrate to CDP Data Hub and use the Operational Database cluster template.

  • Hive or Impala workloads

    If you are running Hive or Impala workloads without HBase: Migrate to Cloudera Data Warehouse.

  • Other workloads

    Migrate to CDP Data Hub and use the custom cluster template.
