// Changes the primary key of a multi-Region key.
//
// This operation changes the replica key in the specified Region to a primary key
// and changes the former primary key to a replica key. For example, suppose you
// have a primary key in us-east-1 and a replica key in eu-west-2 . If you run
// UpdatePrimaryRegion with a PrimaryRegion value of eu-west-2 , the primary key is
// now the key in eu-west-2 , and the key in us-east-1 becomes a replica key. For
// details, see [Updating the primary Region]in the Key Management Service Developer Guide.
//
// This operation supports multi-Region keys, an KMS feature that lets you create
// multiple interoperable KMS keys in different Amazon Web Services Regions.
// Because these KMS keys have the same key ID, key material, and other metadata,
// you can use them interchangeably to encrypt data in one Amazon Web Services
// Region and decrypt it in a different Amazon Web Services Region without
// re-encrypting the data or making a cross-Region call. For more information about
// multi-Region keys, see [Multi-Region keys in KMS]in the Key Management Service Developer Guide.
//
// The primary key of a multi-Region key is the source for properties that are
// always shared by primary and replica keys, including the key material, [key ID], [key spec], [key usage], [key material origin],
// and [automatic key rotation]. It's the only key that can be replicated. You cannot [delete the primary key] until all replica
// keys are deleted.
//
// The key ID and primary Region that you specify uniquely identify the replica
// key that will become the primary key. The primary Region must already have a
// replica key. This operation does not create a KMS key in the specified Region.
// To find the replica keys, use the DescribeKeyoperation on the primary key or any replica
// key. To create a replica key, use the ReplicateKeyoperation.
//
// You can run this operation while using the affected multi-Region keys in
// cryptographic operations. This operation should not delay, interrupt, or cause
// failures in cryptographic operations.
//
// Even after this operation completes, the process of updating the primary Region
// might still be in progress for a few more seconds. Operations such as
// DescribeKey might display both the old and new primary keys as replicas. The old
// and new primary keys have a transient key state of Updating . The original key
// state is restored when the update is complete. While the key state is Updating ,
// you can use the keys in cryptographic operations, but you cannot replicate the
// new primary key or perform certain management operations, such as enabling or
// disabling these keys. For details about the Updating key state, see [Key states of KMS keys] in the Key
// Management Service Developer Guide.
//
// This operation does not return any output. To verify that primary key is
// changed, use the DescribeKeyoperation.
//
// Cross-account use: No. You cannot use this operation in a different Amazon Web
// Services account.
//
// Required permissions:
//
//   - kms:UpdatePrimaryRegion on the current primary key (in the primary key's
//     Region). Include this permission primary key's key policy.
//
//   - kms:UpdatePrimaryRegion on the current replica key (in the replica key's
//     Region). Include this permission in the replica key's key policy.
