Create a target group in Route 53. Set the routing algorithm to Weighted. Configure a weight of 80 for the original resource. Configure a weight of 20 for the new resource.

Create a weighted routing policy. Configure a weight of 80 for the record that points to the original resource. Configure a weight of 20 for the record that points to the new resource.

Create a multivalue answer routing policy. Configure a weight of 80 for the record that points to the original resource. Configure a weight of 20 for the record that points to the new resource. Enable session affinity (sticky sessions).
