**To update AWS CloudFormation stacks** The following ``update-stack`` command updates the template and input parameters for the ``mystack`` stack:: aws cloudformation update-stack --stack-name mystack --template-url https://s3.amazonaws.com/sample/updated.template --parameters ParameterKey=KeyPairName,ParameterValue=SampleKeyPair ParameterKey=SubnetIDs,ParameterValue=SampleSubnetID1\\,SampleSubnetID2 The following ``update-stack`` command updates just the ``SubnetIDs`` parameter value for the ``mystack`` stack. If you don't specify a parameter value, the default value that is specified in the template is used:: aws cloudformation update-stack --stack-name mystack --template-url https://s3.amazonaws.com/sample/updated.template --parameters ParameterKey=KeyPairName,UsePreviousValue=true ParameterKey=SubnetIDs,ParameterValue=SampleSubnetID1\\,UpdatedSampleSubnetID2 The following ``update-stack`` command adds two stack notification topics to the ``mystack`` stack:: aws cloudformation update-stack --stack-name mystack --use-previous-template --notification-arns "arn:aws:sns:use-east-1:123456789012:mytopic1" "arn:aws:sns:us-east-1:123456789012:mytopic2" For more information, see `Updating a Stack`_ in the *AWS CloudFormation User Guide*.
