To plan your upgrade from Ambari managed HDP 2.6.5 to Cloudera Private Cloud Base, you must be aware of the two stages of in-place
upgrade along with the pre-upgrade, upgrade, and post-upgrade tasks.
This upgrade path consists of two stages:
Upgrade HDP 2.6.5 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
2.6.2.x (source) to Ambari 7.1.x.x (target) and then upgrade from HDP
2.6.5 to Cloudera Runtime 7.1.x.
Upgrading and transitioning to Cloudera Private Cloud Base overview:
The final step of the upgrade process is to transition from the Ambari to Cloudera
Manager 7.x.x 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.x.x and activate the Cloudera
Runtime 7.1.x parcels.
Start using the CDP Private Cloud Base cluster with Cloudera Manager
7.x.x.
