To ensure that Redshift clusters receive upgrades automatically during the maintenance window, enable the "Allow Version Upgrade" feature. With this feature enabled, Amazon Redshift engine upgrades, also known as major version upgrades, will occur automatically. This will ensure that the data warehouse service engine has access to the newest features, bug fixes, or the latest security patches released.
To ensure that the Version Upgrade feature is enabled for your Redshift clusters, follow these remediation steps:
- Log in to the AWS Management Console and navigate to the Amazon Redshift dashboard.
- Select the target Redshift cluster.
- Click on the "Properties" tab.
- Scroll down to the "Cluster Upgrade" section.
- Ensure that the "Allow Version Upgrade" option is enabled.
- If the option is disabled, select the checkbox to enable it.
- Click on the "Modify" button to apply the changes.
- Repeat these steps for all Redshift clusters that need to have the Version Upgrade feature enabled.
