The following example shows the AWS CloudTrail log entries that are generated by calling the UpdatePrimaryRegion operation on a multi-Region key.
The UpdatePrimaryRegion operation writes two CloudTrail log entries: one in the
Region with the multi-Region primary key that is converted to a replica key, and one in the
Region with a multi-Region replica key that is converted to a primary key.
CloudTrail log entries for this operation recorded on or after December 2022 include the key ARN of the affected KMS key in the responseElements.keyId value, even though this operation does not return the key ARN.
The following example shows a CloudTrail log entry for UpdatePrimaryRegion in the
Region where the multi-Region key changed from a primary key to a replica key (us-west-2).
The primaryRegion field shows the Region that now hosts the primary key
(ap-northeast-1).

the Region where the multi-Region key changed from a replica key to a primary key
(ap-northeast-1). This log entry doesn't identify the previous primary Region.
