public String getPreSignedUrl() {
        return this.preSignedUrl;
    }
<p>
When you are replicating a DB cluster from one Amazon Web Services GovCloud (US) Region to another, an URL that
contains a Signature Version 4 signed request for the <code>CreateDBCluster</code> operation to be called in the
source Amazon Web Services Region where the DB cluster is replicated from. Specify <code>PreSignedUrl</code> only
when you are performing cross-Region replication from an encrypted DB cluster.
</p>
<p>
The presigned URL must be a valid request for the <code>CreateDBCluster</code> API operation that can run in the
source Amazon Web Services Region that contains the encrypted DB cluster to copy.
</p>
<p>
The presigned URL request must contain the following parameter values:
</p>
<ul>
<li>
<p>
<code>KmsKeyId</code> - 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
<code>CreateDBCluster</code> operation that is called in the destination Amazon Web Services Region, and the
operation contained in the presigned URL.
</p>
</li>
<li>
<p>
<code>DestinationRegion</code> - The name of the Amazon Web Services Region that Aurora read replica will be
created in.
</p>
</li>
<li>
<p>
<code>ReplicationSourceIdentifier</code> - 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
<code>ReplicationSourceIdentifier</code> would look like Example:
<code>arn:aws:rds:us-west-2:123456789012:cluster:aurora-cluster1</code>.
</p>
</li>
</ul>

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