On the Stack Groups page, click the name of the stack group.
In the upper-right corner of the stack group details page, click
and select Update Stack Instance. In the Set Deployment Options step, configure deployment options.
For a self-managed stack group, refer to Step 3: (Optional) Create stack instances to configure the parameters.
For a service-managed stack group, refer to Step 4: (Optional) Create stack instances to configure the parameters.
In the Specify Override Settings step, select the parameters that you want to override, use one of the following methods to reset the parameter values, and then click Next.
Method 1: Choose to reset the parameter values.
