An existing stack can be updated using a new version of AWS CloudFormation template or the same version of the AWS CloudFormation template.
Before starting with stack update, make sure no resource has been deleted manually as it can lead to failures in the stack update procedure.
To update an existing stack to the latest version:
- Locate the Main Stack created using AWS CloudFormation template and Click Update.
Select ‘Replace Current Template’ and paste the URL - https://sumologic-appdev-aws-sam-apps.s3.amazonaws.com/aws-observability-versions/v2.2.0/sumologic_observability.master.template.yaml in the Amazon S3 URL option and select Next.
Keep parameters that you selected before when you created the stack and click Next.
Review all the changes listed on the Change Set Review and make sure you're comfortable with these changes.
Select the capabilities and Click Submit.
After the update is complete, the stacks that have been updated successfully will be set to a UPDATE_COMPLETE status.
