Kubernetes | Rolling Update on Replica Set - kubernetes

Question

I'm trying to perform a rolling update of the container image that my Federated Replica Set is using but I'm getting the following error:
When I run: kubectl rolling-update mywebapp -f mywebapp-v2.yaml
I get the error message: the server could not find the requested resource;
This is a brand new and clean install on Google Container Engine (GKE) so besides creating the Federated Cluster and deploying my first service nothing else has been done. I'm following the instructions from the Kubernetes Docs but no luck.
I've checked to make sure that I'm in the correct context and I've also created a new YAML file pointing to the new image and updated the metadata name. Am I missing something? The easy way for me to do this is to delete the replica set and then redeploy but then I'm cheating myself :). Any pointers would be appreciated
mywebappv2.yaml - new yaml file for rolling update
apiVersion: extensions/v1beta1
kind: ReplicaSet
metadata:
name: mywebapp-v2
spec:
replicas: 4
template:
metadata:
labels:
app: mywebapp
spec:
containers:
- name: mywebapp
image: gcr.io/xxxxxx/static-js:v2

name: mywebapp
My original mywebapp.yaml file:
apiVersion: extensions/v1beta1
kind: ReplicaSet
metadata:
name: mywebapp
spec:
replicas: 4

Try kind: Deployment.
Most kubectl commands that support Replication Controllers also
support ReplicaSets. One exception is the rolling-update command. If
you want the rolling update functionality please consider using
Deployments instead.
Also, the rolling-update command is imperative
whereas Deployments are declarative, so we recommend using Deployments
through the rollout command.
