Quick start: Upgrading CDH to CDP Private Cloud Base

High-level upgrade procedures for upgrades from CDH to CDP Private Cloud Base.

Supported upgrades:

An upgrade from CDH to CDP Private Cloud Base has the following high-level workflow:

  1. Review the Upgrade Guide topic on Supported Upgrade Paths.
  2. Gather information on your deployment. See Getting Started Upgrading Cloudera Manager and Getting Started Upgrading a Cluster.
  3. Plan how and when to begin your upgrade.
  4. Upgrade Cloudera Manager to version 7.1.1 or higher. After upgrading to Cloudera Manager 7.1.1 or higher, Cloudera Manager will manage upgrading your cluster to a higher version. See Upgrading Cloudera Manager.
  5. Perform any needed pre-upgrade transition steps for the components deployed in your clusters. See CDP Private Cloud Base Pre-upgrade steps
  6. Use Cloudera Manager to Upgrade CDH to Cloudera Runtime 7, or from Cloudera Runtime to a higher version of Cloudera Runtime. See Upgrading a cluster.
  7. Perform any needed post-upgrade transition steps for the components deployed in your clusters. See Post-CDP upgrade transitions.
