It seems that it is not possible to create multiple different versions of mysql services in one k8s?

1. my first yaml
   `apiVersion: mysql.presslabs.org/v1alpha1
   kind: MysqlCluster
   metadata:
   name: my-cluster
   spec:
   replicas: 2
   secretName: my-cluster-secret
   image: percona:5.7
   mysqlVersion: "5.7"
   volumeSpec:
   persistentVolumeClaim:
   accessModes: [ "ReadWriteOnce" ]
   resources:
   requests:
   storage: 10Gi
   storageClassName: csi-disk

---

apiVersion: v1
kind: Secret
metadata:
name: my-cluster-secret
type: Opaque
data:
ROOT_PASSWORD: $(echo -n "not-so-secure" | base64)`

2. second yaml file
   `apiVersion: mysql.presslabs.org/v1alpha1
   kind: MysqlCluster
   metadata:
   name: my-cluster-8.0
   spec:
   replicas: 2
   secretName: my-cluster-secret-8.0
   image: percona:8.0.33-25
   mysqlVersion: "8.0.33"
   volumeSpec:
   persistentVolumeClaim:
   accessModes: [ "ReadWriteOnce" ]
   resources:
   requests:
   storage: 10Gi
   storageClassName: csi-disk

---

apiVersion: v1
kind: Secret
metadata:
name: my-cluster-secret
type: Opaque
data:
ROOT_PASSWORD: $(echo -n "not-so-secure" | base64)`

my question is : Executing the second yaml file operator doesn't seem to work.
Thank you for any reply:)

Is there any error log in operator?
