changeSetType

The type of the change set. Valid values: CREATE: creates a change set for a new stack. UPDATE: creates a change set for an existing stack. IMPORT: creates a change set for a new stack or an existing stack to import non-ROS-managed resources. If you create a change set for a new stack, ROS creates a stack that has a unique stack ID. The stack is in the REVIEW_IN_PROGRESS state until you execute the change set. You cannot use the UPDATE type to create a change set for a new stack or the CREATE type to create a change set for an existing stack.
