In-place upgrade overview
To plan your upgrade from Ambari managed HDP 2.6.5 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 2.6.5 to Cloudera Runtime 7.1.x using Ambari.
- Transition the management platform from Ambari to Cloudera Manager.
Upgrading and transitioning to CDP 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.
- Uninstall Ambari and the HDP stack
Troubleshooting: A selection of Cloudera Knowledge Base articles are available that describe common issues encountered by Cloudera customers during upgrades and migrations. See CDP Upgrade/Migrate Troubleshooting Articles. (Cloudera login required.)
