Upgrading PostgreSQL 9.6 before EOL You need to plan for the end-of-life (EOL) of PostgresSQL 9.6, announced by Amazon. As an AWS environment user, you need to check the version of PostgreSQL you use for Cloudera Data Warehouse environments. If your database version is still PostgreSQL 9.6, you need to upgrade to PostgreSQL 11.12. Helm 2 to Helm 3 migration on AWS environments for Cloudera Data Warehouse Helm is a package manager for the Kubernetes platform. Cloudera Data Warehouse (CDW), which runs on Kubernetes, has migrated to Helm version 3 to take advantage of the improved security and upgrading capabilities. Existing environments that were activated on Helm 2 have limitations. Upgrading an Amazon Kubernetes Service cluster for CDW To avoid compatibility issues between Cloudera Data Warehouse (CDW) and AWS resources, the version of Kubernetes that supports your CDW clusters should be upgraded if supported by Cloudera. Upgrading using your own AMI or reduced permissions You learn the prerequisite for using your own AMI, the risks of using your own AMI, and the steps involved in upgrading.
