What happens if you apply a CloudFormation in Kion that already exists in an AWS account?


Kion will start actively managing the CloudFormation policy. This means Kion will perform an `UpdateStack` operation on the stack so it matches the CloudFormation in Kion. If it's the same stack body and parameters, then no changes are performed. If it's different, then the stack will be changed to match what is in Kion.

We designed the software to allow you to easily transition over your CloudFormation templates over without having to remove them and then re-apply them to your AWS account.

Kion will do the same thing for IAM policies.
