  3. Modify Cluster: In the cluster details page, click on the “Modify” button to make changes to the cluster configuration.
  4. Enable Automatic Version Upgrade: Scroll down to the “Cluster Version” section of the Modify Cluster page. Check the box next to “Automatic Upgrade” to enable automatic version upgrades.
  5. Save Changes: After enabling automatic version upgrades, click on the “Apply Changes” button to save the configuration.
  6. Monitor Cluster Upgrades: Once automatic version upgrades are enabled, Redshift will automatically upgrade your cluster to the latest available version during the maintenance window. You can monitor the upgrade progress and status in the cluster details page.
