Redshift Clusters Should Allow Version Upgrade
More Info:
Version Upgrade should be enabled for Redshift clusters to automatically receive upgrades during the maintenance window.

Triage and Remediation
Remediation
To remediate the misconfiguration where Redshift clusters do not allow version upgrades in AWS, you can follow these steps using the AWS Management Console:
-
Navigate to the Amazon Redshift Console:
- Open a web browser and go to the AWS Management Console.
- In the “Find services” search bar, type “Redshift” and select it from the options that appear.
-
Select the Redshift Cluster:
- In the Amazon Redshift console, select the Redshift cluster for which you want to enable version upgrades.
-
Modify the Cluster:
- In the cluster details page, click on the “Clusters” tab and select the cluster you want to modify.
- Click on the “Modify” button at the top of the page.
-
Enable Version Upgrade:
- In the “Modify cluster” page, scroll down to the “Cluster permissions and maintenance” section.
- Look for the “Allow version upgrade” option and check the box next to it to enable version upgrades for the cluster.
-
Save Changes:
- Scroll down to the bottom of the page and click on the “Modify cluster” button to save the changes.
-
Monitor the Upgrade:
- Once the modification is complete, AWS Redshift will start the version upgrade process for the cluster.
- You can monitor the progress of the upgrade in the Amazon Redshift console.
By following these steps, you can successfully remediate the misconfiguration and allow version upgrades for your AWS Redshift clusters.
To remediate the misconfiguration where Redshift clusters do not allow version upgrade in AWS, you can follow these steps using AWS CLI:
- List the existing Redshift clusters to identify the cluster that needs to be updated:
aws redshift describe-clusters --query 'Clusters[*].[ClusterIdentifier,ClusterVersion]' --output table
- Modify the Redshift cluster parameter group to allow version upgrade:
aws redshift modify-cluster --cluster-identifier <cluster-identifier> --allow-version-upgrade
Replace <cluster-identifier> with the identifier of the Redshift cluster that needs to allow version upgrade.
- Verify the modification status to ensure the version upgrade is allowed:
aws redshift describe-clusters --cluster-identifier <cluster-identifier> --query 'Clusters[*].[ClusterIdentifier,AllowVersionUpgrade]' --output table
Replace <cluster-identifier> with the identifier of the Redshift cluster.
- If the modification is successful, you can proceed with upgrading the Redshift cluster to the desired version. You can use the following command to upgrade the Redshift cluster:
aws redshift modify-cluster --cluster-identifier <cluster-identifier> --cluster-version <desired-version>
Replace <cluster-identifier> with the identifier of the Redshift cluster and <desired-version> with the version you want to upgrade to.
By following these steps, you can remediate the misconfiguration and allow version upgrade for Redshift clusters in AWS using AWS CLI.
To remediate the misconfiguration where Redshift clusters do not allow version upgrades, you can use the AWS SDK for Python (Boto3) to modify the cluster parameter group associated with the Redshift cluster. Here are the steps to remediate this issue:
- Install Boto3: If you haven’t already installed the Boto3 library, you can do so using pip:
pip install boto3
- Update the Redshift Cluster Parameter Group: Use the following Python script to update the Redshift cluster parameter group to allow version upgrades:
import boto3
# Initialize the Redshift client
redshift_client = boto3.client('redshift')
# Specify the cluster identifier for the Redshift cluster
cluster_identifier = 'your-redshift-cluster-identifier'
# Specify the parameter group name associated with the Redshift cluster
parameter_group_name = 'your-redshift-parameter-group-name'
# Update the cluster parameter group to allow version upgrades
response = redshift_client.modify_cluster_parameter_group(
ParameterGroupName=parameter_group_name,
Parameters=[
{
'ParameterName': 'allow_version_upgrade',
'ParameterValue': 'true',
'Description': 'Allow version upgrade for Redshift cluster',
'Source': 'user'
},
]
)
# Print the response
print(response)
-
Replace the placeholders ‘your-redshift-cluster-identifier’ and ‘your-redshift-parameter-group-name’ with the actual values for your Redshift cluster.
-
Run the Python script: Save the above script in a Python file (e.g., update_redshift_parameter_group.py) and run it using the Python interpreter:
python update_redshift_parameter_group.py
After running the script, the Redshift cluster parameter group will be updated to allow version upgrades. You can verify the changes in the AWS Management Console or by describing the cluster parameter group using the Boto3 SDK.
