Update the solution

If you have previously deployed this solution, follow this procedure to update the Landing Zone Accelerator on AWS CloudFormation stack to get the latest version of the solution’s framework.

Before updating the solution, run the Core pipeline manually on your current version. Troubleshoot any existing issues so that your current version runs smoothly. Performing a dry run of your existing version before proceeding with the following instructions ensures that there is no drift and the environment is stable.

1. Sign in to the AWS CloudFormation console, select your existing Landing Zone Accelerator on AWS CloudFormation stack, and select Update.

2. Select Replace current template.

3. Under Specify template:

   1. Select Amazon S3 URL.

   2. Copy the link of the latest template.

   3. Paste the link in the Amazon S3 URL box.

   4. Verify that the correct template URL shows in the Amazon S3 URL text box, and choose Next. Choose Next again.

4. Under Parameters, review the parameters for the template and modify them as necessary. At minimum, modify the Branch Name parameter to the release branch of the version you are updating to. Refer to Step 1. Launch the stack for details about the parameters.

5. Choose Next.

6. On the Configure stack options page, choose Next.

7. On the Review page, review and confirm the settings. Check the box acknowledging that the template might create IAM resources.

8. Choose View change set and verify the changes.

9. Choose Update stack to deploy the stack.

Updating the solution automatically invokes the Core pipeline (AWSAccelerator-PipelineStack*). You can view the status of the stack in the AWS CloudFormation console in the Status column. You should receive a UPDATE_COMPLETE status in approximately 10 minutes.
