    #   with the same KMS key as the source DB cluster snapshot.
    #
    #   If you copy an encrypted DB cluster snapshot that is shared from
    #   another Amazon Web Services account, then you must specify a value

    #
    #   To copy an encrypted DB cluster snapshot to another Amazon Web

    #   Signature Version 4 signed request for the `CopyDBClusterSnapshot`
    #   API operation in the Amazon Web Services Region that contains the
    #   source DB cluster snapshot to copy. Use the `PreSignedUrl` parameter
    #   when copying an encrypted DB cluster snapshot from another Amazon
    #   Web Services Region. Don't specify `PreSignedUrl` when copying an
    #   encrypted DB cluster snapshot in the same Amazon Web Services
    #   Region.
    #
    #   This setting applies only to Amazon Web Services GovCloud (US)
    #   Regions. It's ignored in other Amazon Web Services Regions.
    #
    #   The presigned URL must be a valid request for the
    #   `CopyDBClusterSnapshot` API operation that can run in the source
    #   Amazon Web Services Region that contains the encrypted DB cluster
    #   snapshot to copy. The presigned URL request must contain the
    #   following parameter values:
    #
    #   * `KmsKeyId` - The KMS key identifier for the KMS key to use to
    #     encrypt the copy of the DB cluster snapshot in the destination
    #     Amazon Web Services Region. This is the same identifier for both
    #     the `CopyDBClusterSnapshot` operation that is called in the
    #     destination Amazon Web Services Region, and the operation
    #     contained in the presigned URL.
    #
    #   * `DestinationRegion` - The name of the Amazon Web Services Region
    #     that the DB cluster snapshot is to be created in.
    #
    #   * `SourceDBClusterSnapshotIdentifier` - The DB cluster snapshot
    #     identifier for the encrypted DB cluster snapshot to be copied.
    #     This identifier must be in the Amazon Resource Name (ARN) format
    #     for the source Amazon Web Services Region. For example, if you are
    #     copying an encrypted DB cluster snapshot from the us-west-2 Amazon
    #     Web Services Region, then your `SourceDBClusterSnapshotIdentifier`
    #     looks like the following example:
    #     `arn:aws:rds:us-west-2:123456789012:cluster-snapshot:aurora-cluster1-snapshot-20161115`.
    #

    #   Process][2].
    #
    #   <note markdown="1"> If you are using an Amazon Web Services SDK tool or the CLI, you can
    #   specify `SourceRegion` (or `--source-region` for the CLI) instead of
    #   specifying `PreSignedUrl` manually. Specifying `SourceRegion`
    #   autogenerates a presigned URL that is a valid request for the
    #   operation that can run in the source Amazon Web Services Region.

    #
    #   * `DestinationRegion` - The Amazon Web Services Region that the
    #     encrypted DB snapshot is copied to. This Amazon Web Services
    #     Region is the same one where the `CopyDBSnapshot` operation is

    #     For example, if you copy an encrypted DB snapshot from the
    #     us-west-2 Amazon Web Services Region to the us-east-1 Amazon Web
    #     Services Region, then you call the `CopyDBSnapshot` operation in

    #     `DestinationRegion` in the presigned URL must be set to the
    #     us-east-1 Amazon Web Services Region.
    #
    #   * `KmsKeyId` - The KMS key identifier for the KMS key to use to
    #     encrypt the copy of the DB snapshot in the destination Amazon Web
    #     Services Region. This is the same identifier for both the
    #     `CopyDBSnapshot` operation that is called in the destination
    #     Amazon Web Services Region, and the operation contained in the
    #     presigned URL.
    #
    #   * `SourceDBSnapshotIdentifier` - The DB snapshot identifier for the
    #     encrypted snapshot to be copied. This identifier must be in the
    #     Amazon Resource Name (ARN) format for the source Amazon Web
    #     Services Region. For example, if you are copying an encrypted DB
    #     snapshot from the us-west-2 Amazon Web Services Region, then your
    #     `SourceDBSnapshotIdentifier` looks like the following example:
    #     `arn:aws:rds:us-west-2:123456789012:snapshot:mysql-instance1-snapshot-20161115`.

    #   <note markdown="1"> If you are using an Amazon Web Services SDK tool or the CLI, you can
    #   specify `SourceRegion` (or `--source-region` for the CLI) instead of
    #   specifying `PreSignedUrl` manually. Specifying `SourceRegion`
    #   autogenerates a presigned URL that is a valid request for the
    #   operation that can run in the source Amazon Web Services Region.

    #   When a KMS key isn't specified in `KmsKeyId`:
    #
    #   * If `ReplicationSourceIdentifier` identifies an encrypted source,
    #     then Amazon RDS uses the KMS key used to encrypt the source.

    # @!attribute [rw] pre_signed_url
    #   When you are replicating a DB cluster from one Amazon Web Services

    #   Version 4 signed request for the `CreateDBCluster` operation to be
    #   called in the source Amazon Web Services Region where the DB cluster
    #   is replicated from. Specify `PreSignedUrl` only when you are
    #   performing cross-Region replication from an encrypted DB cluster.
    #
    #   The presigned URL must be a valid request for the `CreateDBCluster`
    #   API operation that can run in the source Amazon Web Services Region
    #   that contains the encrypted DB cluster to copy.
    #
    #   The presigned URL request must contain the following parameter
    #   values:
    #
    #   * `KmsKeyId` - The KMS key identifier for the KMS key to use to
    #     encrypt the copy of the DB cluster in the destination Amazon Web
    #     Services Region. This should refer to the same KMS key for both
    #     the `CreateDBCluster` operation that is called in the destination
    #     Amazon Web Services Region, and the operation contained in the
    #     presigned URL.
    #
    #   * `DestinationRegion` - The name of the Amazon Web Services Region
    #     that Aurora read replica will be created in.
    #
    #   * `ReplicationSourceIdentifier` - The DB cluster identifier for the
    #     encrypted DB cluster to be copied. This identifier must be in the
    #     Amazon Resource Name (ARN) format for the source Amazon Web
    #     Services Region. For example, if you are copying an encrypted DB
    #     cluster from the us-west-2 Amazon Web Services Region, then your
    #     `ReplicationSourceIdentifier` would look like Example:
    #     `arn:aws:rds:us-west-2:123456789012:cluster:aurora-cluster1`.
    #
    #   To learn how to generate a Signature Version 4 signed request, see [
    #   Authenticating Requests: Using Query Parameters (Amazon Web Services
    #   Signature Version 4)][1] and [ Signature Version 4 Signing
    #   Process][2].
    #
    #   <note markdown="1"> If you are using an Amazon Web Services SDK tool or the CLI, you can
    #   specify `SourceRegion` (or `--source-region` for the CLI) instead of
    #   specifying `PreSignedUrl` manually. Specifying `SourceRegion`
    #   autogenerates a presigned URL that is a valid request for the
    #   operation that can run in the source Amazon Web Services Region.

    #
    #   If you create an encrypted read replica in the same Amazon Web
    #   Services Region as the source DB instance or Multi-AZ DB cluster,
    #   don't specify a value for this parameter. A read replica in the

    #   KMS key as the source DB instance or cluster.
    #
    #   If you create an encrypted read replica in a different Amazon Web
    #   Services Region, then you must specify a KMS key identifier for the
    #   destination Amazon Web Services Region. KMS keys are specific to the
    #   Amazon Web Services Region that they are created in, and you can't
    #   use KMS keys from one Amazon Web Services Region in another Amazon
    #   Web Services Region.
    #
    #   You can't create an encrypted read replica from an unencrypted DB

    #   Services Region to another, the URL that contains a Signature
    #   Version 4 signed request for the `CreateDBInstanceReadReplica` API
    #   operation in the source Amazon Web Services Region that contains the
    #   source DB instance.
    #
    #   This setting applies only to Amazon Web Services GovCloud (US)
    #   Regions and China Amazon Web Services Regions. It's ignored in
    #   other Amazon Web Services Regions.
    #
    #   This setting applies only when replicating from a source DB
    #   *instance*. Source DB clusters aren't supported in Amazon Web
    #   Services GovCloud (US) Regions and China Amazon Web Services
    #   Regions.
    #
    #   You must specify this parameter when you create an encrypted read
    #   replica from another Amazon Web Services Region by using the Amazon
    #   RDS API. Don't specify `PreSignedUrl` when you are creating an
    #   encrypted read replica in the same Amazon Web Services Region.
    #
    #   The presigned URL must be a valid request for the
    #   `CreateDBInstanceReadReplica` API operation that can run in the
    #   source Amazon Web Services Region that contains the encrypted source
    #   DB instance. The presigned URL request must contain the following
    #   parameter values:
    #
    #   * `DestinationRegion` - The Amazon Web Services Region that the
    #     encrypted read replica is created in. This Amazon Web Services
    #     Region is the same one where the `CreateDBInstanceReadReplica`
    #     operation is called that contains this presigned URL.
    #
    #     For example, if you create an encrypted DB instance in the
    #     us-west-1 Amazon Web Services Region, from a source DB instance in
    #     the us-east-2 Amazon Web Services Region, then you call the
    #     `CreateDBInstanceReadReplica` operation in the us-east-1 Amazon
    #     Web Services Region and provide a presigned URL that contains a
    #     call to the `CreateDBInstanceReadReplica` operation in the
    #     us-west-2 Amazon Web Services Region. For this example, the
    #     `DestinationRegion` in the presigned URL must be set to the
    #     us-east-1 Amazon Web Services Region.
    #
    #   * `KmsKeyId` - The KMS key identifier for the key to use to encrypt
    #     the read replica in the destination Amazon Web Services Region.
    #     This is the same identifier for both the
    #     `CreateDBInstanceReadReplica` operation that is called in the
    #     destination Amazon Web Services Region, and the operation
    #     contained in the presigned URL.
    #
    #   * `SourceDBInstanceIdentifier` - The DB instance identifier for the
    #     encrypted DB instance to be replicated. This identifier must be in
    #     the Amazon Resource Name (ARN) format for the source Amazon Web
    #     Services Region. For example, if you are creating an encrypted
    #     read replica from a DB instance in the us-west-2 Amazon Web
    #     Services Region, then your `SourceDBInstanceIdentifier` looks like
    #     the following example:
    #     `arn:aws:rds:us-west-2:123456789012:instance:mysql-instance1-20161115`.
    #
    #   To learn how to generate a Signature Version 4 signed request, see
    #   [Authenticating Requests: Using Query Parameters (Amazon Web
    #   Services Signature Version 4)][1] and [Signature Version 4 Signing
    #   Process][2].
    #
    #   <note markdown="1"> If you are using an Amazon Web Services SDK tool or the CLI, you can
    #   specify `SourceRegion` (or `--source-region` for the CLI) instead of
    #   specifying `PreSignedUrl` manually. Specifying `SourceRegion`
    #   autogenerates a presigned URL that is a valid request for the
    #   operation that can run in the source Amazon Web Services Region.

    #   * The DB instance doesn't manage the master user password in Amazon
    #     Web Services Secrets Manager.

    #     If the DB instance already manages the master user password in
    #     Amazon Web Services Secrets Manager, you can't change the KMS key
    #     used to encrypt the secret.
    #
    #   * You are turning on `ManageMasterUserPassword` to manage the master
    #     user password in Amazon Web Services Secrets Manager.
    #
    #     If you are turning on `ManageMasterUserPassword` and don't
    #     specify `MasterUserSecretKmsKeyId`, then the `aws/secretsmanager`
    #     KMS key is used to encrypt the secret. If the secret is in a
    #     different Amazon Web Services account, then you can't use the
    #     `aws/secretsmanager` KMS key to encrypt the secret, and you must
    #     use a customer managed KMS key.
    #
    #   The Amazon Web Services KMS key identifier is the key ARN, key ID,
    #   alias ARN, or alias name for the KMS key. To use a KMS key in a
    #   different Amazon Web Services account, specify the key ARN or alias
    #   ARN.

    #   * Make sure that you specify `oracle-ee-cdb` or `oracle-se2-cdb`.
    #
    #   * Make sure that your DB engine runs Oracle Database 19c with an
    #     April 2021 or later RU.
    #
    #   Note the following limitations:
    #
    #   * You can't convert a CDB to a non-CDB.
    #
    #   * You can't convert a replica database.
    #
    #   * You can't convert a non-CDB to a CDB and upgrade the engine
    #     version in the same command.
    #
    #   * You can't convert the existing custom parameter or option group
    #     when it has options or parameters that are permanent or
    #     persistent. In this situation, the DB instance reverts to the
    #     default option and parameter group. To avoid reverting to the
    #     default, specify a new parameter group with
    #     `--db-parameter-group-name` and a new option group with

    #   Specifies whether the to convert your DB instance from the
    #   single-tenant configuration to the multi-tenant configuration. This
    #   parameter is supported only for RDS for Oracle CDB instances.
    #
    #   During the conversion, RDS creates an initial tenant database and
    #   associates the DB name, master user name, character set, and
    #   national character set metadata with this database. The tags
    #   associated with the instance also propagate to the initial tenant
    #   database. You can add more tenant databases to your DB instance by
    #   using the `CreateTenantDatabase` operation.
    #
    #   The conversion to the multi-tenant configuration is permanent and
    #   irreversible, so you can't later convert back to the single-tenant
    #   configuration. When you specify this parameter, you must also
    #   specify `ApplyImmediately`.

    #   The Amazon Web Services KMS key identifier is the key ARN, key ID,
    #   alias ARN, or alias name for the KMS key. To use a KMS key in a
    #   different Amazon Web Services account, specify the key ARN or alias
    #   ARN.
    #
    #   You can restore to a new DB cluster and encrypt the new DB cluster
    #   with a KMS key that is different from the KMS key used to encrypt
    #   the source DB cluster. The new DB cluster is encrypted with the KMS
    #   key identified by the `KmsKeyId` parameter.
    #
    #   If you don't specify a value for the `KmsKeyId` parameter, then the
    #   following occurs:
    #
    #   * If the DB cluster is encrypted, then the restored DB cluster is
    #     encrypted using the KMS key that was used to encrypt the source DB
    #     cluster.
    #
    #   * If the DB cluster isn't encrypted, then the restored DB cluster
    #     isn't encrypted.
    #
    #   If `DBClusterIdentifier` refers to a DB cluster that isn't
    #   encrypted, then the restore request is rejected.
