Version Upgrade should be enabled for Redshift clusters to automatically receive upgrades during the maintenance window.
1. Run modify-cluster command (OSX/Linux/UNIX) using the name of the cluster that you want to update as identifier to enable AWS Redshift engine version upgrades for the selected cluster.
Eg: aws redshift modify-cluster --region us-east-1 --cluster-identifier cc-cluster --allow-version-upgrade
2. If successful, the command output should return the Redshift cluster new configuration metadata
