Update the solution
If you have previously deployed the solution, follow this procedure to update the solution's CloudFormation stack to get the latest version of the solution's framework.
Important
The Amazon VPC and related resource configuration cannot be updated using the CloudFormation update stack workflow. To update the VPC CIDR block, you must delete and recreate the VPC. We recommend consulting your network engineering team to obtain a dedicated CIDR block for the inspection VPC.

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 7–10 minutes.
Update the Network Firewall log destination
If you previously deployed this solution, any updates made to the stack will require you to manually initiate CodePipeline to update to the Network Firewall log destination. The Network Firewall configuration should not be updated to manually release changes. To start the AWS CodePipeline manually, refer to Start a pipeline manually in the AWS CodePipeline User Guide.
To modify the AWS Network Firewall, firewall policy, and rule groups, refer to Configuring resources for network firewall.
