// 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:
//   - An existing virtual private gateway to a new virtual private gateway
//   - An existing virtual private gateway to a transit gateway
//   - An existing transit gateway to a new transit gateway
//   - An existing transit gateway to a virtual private gateway
//
// Before you perform the migration to the new gateway, you must configure the new
// gateway. Use CreateVpnGateway to create a virtual private gateway, or
// CreateTransitGateway to create a transit gateway. This step is required when you
// migrate from a virtual private gateway with static routes to a transit gateway.
// You must delete the static routes before you migrate to the new gateway. 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.
// After you migrate to the new gateway, you might need to modify your VPC route
// table. Use CreateRoute and DeleteRoute to make the changes described in Update
// VPC route tables (https://docs.aws.amazon.com/vpn/latest/s2svpn/modify-vpn-target.html#step-update-routing)
// in the Amazon Web Services Site-to-Site VPN User Guide. 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
// CreateTransitGatewayRoute to add the routes. If you deleted VPN static routes,
// you must add the static routes to the transit gateway route table. 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.
