[dpappa]

https://artifacthub.io/packages/helm/aws/aws-load-balancer-controller/1.13.4#upgrading-from-aws-load-balancer-controller-v2-1-3-and-earlier

Additional IAM permissions required, ensure you have granted the required IAM permissions.
CRDs need to be updated as follows
kubectl apply -k "github.com/aws/eks-charts/stable/aws-load-balancer-controller//crds?ref=master"
you can run helm upgrade without uninstalling the old chart completely
