To plan your upgrade from Ambari managed HDP 3.1.5 to CDP 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 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.
