An Overview of the Upgrade Process

This document provides instructions on upgrading from Ambari managed HDP 2.6.5.x to CDP Private Cloud Base.

This upgrade path consists of two stages:
  1. Upgrade HDP 2.6.5.x to Cloudera Runtime 7.1.x using Ambari.
  2. Transition the management platform from Ambari to Cloudera Manager
To upgrade to Cloudera Runtime 7.1.x, you must first upgrade from Ambari 2.6.2.x (source) to Ambari 7.1.x.x (target) and then upgrade from HDP 2.6.5.x to Cloudera Runtime 7.1.x. The final step of the upgrade process is to transition from the Ambari to Cloudera Manager 7.1.x using the AM2CM tool.

The HDP Cluster’s blueprint is captured from Ambari and converted to a Cloudera Manager deployment template using the AM2CM tool. You can then deploy the template to Cloudera Manager 7.1.x and activate the Cloudera Runtime 7.1.x parcels. You can now start using the CDP Private Cloud Base cluster with Cloudera Manager 7.1.x and uninstall the Ambari-managed HDP stack and Ambari 7.1.x.x

Go through Upgrading and transitioning to CDP Private Cloud Base to understand the steps that you must perform to complete the HDP to CDP Private Cloud Base upgrade.
