Before you upgrade
This section explains how to upgrade Ambari.
Upgrading Ambari is much like any other upgrade in HDP. The main difference here is that the underlying platform is running Cloudera Runtime bits for all services. This is important because it provides an upgrade path to using the latest bits of the underlying stack. These include upgrades to HDFS, Hive, Spark, Ranger, Oozie, HBase, and so on.
Ambari and the HDP intermediate bits clusters being managed by Ambari can be upgraded independently. This section describes the process to upgrade Ambari. You are encouraged to read completely through this entire document before starting the upgrade process, so that you understand the interdependencies and order of the steps. It is recommended you validate these steps in a test environment to adjust and account for any special configurations for your cluster.
