You can call this operation to update a stack instance in a specific account in a region.
If you have updated a stack group, you can call the UpdateStackInstances operation to update the stack instances in the stack group and the stack template corresponding to the stack instances.
In this example, stack instances of the 151266687691****
and 141261387191****
Alibaba Cloud accounts in the China (Hangzhou) and China (Beijing) regions are updated.
The stack instances belong to a stack group named MyStackGroup
.
