updateStackSet

Updates the StackSet and associated stack instances in the specified accounts and Amazon Web Services Regions.

Even if the StackSet operation created by updating the StackSet fails (completely or partially, below or above a specified failure tolerance), the StackSet is updated with your changes. Subsequent CreateStackInstances calls on the specified StackSet use the updated StackSet.

The maximum number of organizational unit (OUs) supported by a UpdateStackSet operation is 50.

If you need more than 50, consider the following options:

• Batch processing: If you don't want to expose your OU hierarchy, split up the operations into multiple calls with less than 50 OUs each.

• Parent OU strategy: If you don't mind exposing the OU hierarchy, target a parent OU that contains all desired child OUs.
