Hello people!

A week ago, I used:

`kubectl apply -f https://download.elastic.co/downloads/eck/1.0.0/all-in-one.yaml`

and created an ES cluster in a Kubernetes (deployed in EC2 instances), of version 7.5.2.

## Today, as I wanted to upgrade to the 7.6.0 version, I changed the yaml of the Cluster:

```
apiVersion: elasticsearch.k8s.elastic.co/v1
kind: Elasticsearch
metadata:
  name: elastic
spec:
  version: 7.6.0 # <-- Here
  updateStrategy:
    changeBudget:
      maxSurge: -1
      maxUnavailable: 0

```

* * *

Now I get the following:

```
$ k get elasticsearches.elasticsearch.k8s.elastic.co 
NAME HEALTH NODES VERSION PHASE AGE
elastic green 3 7.6.0 6d

```

But the Service itself responds with:

```
{
  "name" : "elastic-es-default-1",
  "cluster_name" : "elastic",
  "cluster_uuid" : "[...]",
  "version" : {
    "number" : "7.5.2",

```

Is there something that I am missing?

P.S The error seems the following:

```
kubectl describe elasticsearches.elasticsearch.k8s.elastic.co 
  Version: 7.6.0
Status:
  Available Nodes: 3
  Health: green
Events:
  Type Reason Age From Message
  ---- ------ ---- ---- -------

```
