1. Log in to your GCP console.
2. Go to the Cloud SQL Instances page.
3. Select the SQL instance that you want to remediate.
4. Click on the “Edit” button at the top of the page.
5. Scroll down to the “Configuration options” section.
6. Under the “Backend Type” option, select “Second Generation” from the dropdown menu.
7. Click on the “Save” button at the bottom of the page.
8. Wait for the changes to take effect. This may take a few minutes.

​

1. Open the Google Cloud Console and navigate to the Cloud Shell.
2. Run the following command to list all the existing SQL instances:

gcloud sql instances list

3. Identify the SQL instance that needs to be updated and note down its name.
4. Run the following command to update the SQL instance with the Second Generation backend type:

gcloud sql instances patch [INSTANCE_NAME] --database-version=MYSQL_5_7 --storage-auto-increase

5. Wait for the update to complete. This may take a few minutes.
6. Run the following command to verify that the SQL instance has been updated:

gcloud sql instances describe [INSTANCE_NAME]

7. Verify that your application is still functioning as expected.

1. First, you need to get a list of all the SQL instances in your GCP project using the Cloud SQL Admin API. You can use the following code to get the list of SQL instances:

from google.oauth2 import service_account
from googleapiclient.discovery import build

# Set up credentials
credentials = service_account.Credentials.from_service_account_file(
    'path/to/credentials.json')

# Set up the Cloud SQL Admin API client
service = build('sqladmin', 'v1beta4', credentials=credentials)

# Get a list of all the SQL instances in the project
instances = service.instances().list(project='my-project').execute()

2. Once you have the list of SQL instances, you can loop through each instance and check if it has a backend type of “SECOND_GEN”. If not, you can update the instance’s backend type using the patch method of the Cloud SQL Admin API. Here’s the code to do that:

# Loop through each SQL instance
for instance in instances['items']:
    # Check if the backend type is SECOND_GEN
    if instance['backendType'] != 'SECOND_GEN':
        # Update the instance's backend type to SECOND_GEN
        patch_body = {
            'backendType': 'SECOND_GEN'
        }
        service.instances().patch(
            project='my-project',
            instance=instance['name'],
            body=patch_body).execute()

3. Finally, you can verify that the backend type of all the SQL instances has been updated to “SECOND_GEN” by re-running the code to get the list of instances and checking their backend types.
