This document provides instructions on upgrading from Ambari managed HDP 3.1.5 to CDP Private Cloud Base.
This upgrade path consists of two stages:
Upgrade HDP 3.1.5 to Cloudera Runtime 7.1.x using Ambari.
Transition the management platform from Ambari to Cloudera Manager.
To upgrade to Cloudera Runtime 7.1.x, you must first upgrade from Ambari
2.7.5.x (source) to Ambari 7.1.x.x (target) and then upgrade from
HDP 3.1.5 to Cloudera Runtime 7.1.x. The final step of the upgrade process is to transition from the Ambari to
Cloudera Manager 7.3.1 using the AM2CM tool. It includes the
following steps:
HDP cluster blueprint is exported from Ambari and converted to a Cloudera
Manager deployment template using the AM2CM tool.
Deploy the template to Cloudera Manager 7.3.1 and activate the Cloudera
Runtime 7.1.x parcels.
Start using the CDP Private Cloud Base cluster with Cloudera Manager
7.3.1.
Uninstall Ambari and the HDP stack
