/**
 * <p>Modifies the customer gateway or the target gateway of an Amazon Web Services Site-to-Site VPN connection. To
 *             modify the target gateway, the following migration options are available:</p>
 *          <ul>
 *             <li>
 *                <p>An existing virtual private gateway to a new virtual private gateway</p>
 *             </li>
 *             <li>
 *                <p>An existing virtual private gateway to a transit gateway</p>
 *             </li>
 *             <li>
 *                <p>An existing transit gateway to a new transit gateway</p>
 *             </li>
 *             <li>
 *                <p>An existing transit gateway to a virtual private gateway</p>
 *             </li>
 *          </ul>
 *          <p>Before you perform the migration to the new gateway, you must configure the new
 *             gateway. Use <a>CreateVpnGateway</a> to create a virtual private gateway, or
 *                 <a>CreateTransitGateway</a> to create a transit gateway.</p>
 *          <p>This step is required when you migrate from a virtual private gateway with static
 *             routes to a transit gateway. </p>
 *          <p>You must delete the static routes before you migrate to the new gateway.</p>
 *          <p>Keep a copy of the static route before you delete it. You will need to add back these
 *             routes to the transit gateway after the VPN connection migration is complete.</p>
 *          <p>After you migrate to the new gateway, you might need to modify your VPC route table.
 *             Use <a>CreateRoute</a> and <a>DeleteRoute</a> to make the changes
 *             described in <a href="https://docs.aws.amazon.com/vpn/latest/s2svpn/modify-vpn-target.html#step-update-routing">Update VPC route
 *                 tables</a> in the <i>Amazon Web Services Site-to-Site VPN User Guide</i>.</p>
 *          <p>When the new gateway is a transit gateway, modify the transit gateway route table to
 *             allow traffic between the VPC and the Amazon Web Services Site-to-Site VPN connection.
 *             Use <a>CreateTransitGatewayRoute</a> to add the routes.</p>
 *          <p> If you deleted VPN static routes, you must add the static routes to the transit
 *             gateway route table.</p>
 *          <p>After you perform this operation, the VPN endpoint's IP addresses on the Amazon Web Services side and the tunnel options remain intact. Your Amazon Web Services Site-to-Site VPN connection will
 *             be temporarily unavailable for a brief period while we provision the new
 *             endpoints.</p>

 * Use a bare-bones client and the command you need to make an API call.
