**Kibana version** : 8.14.3  
**Elasticsearch version** : 8.14.3  
**APM Server version** : 8.14.3  
**Original install method** : Migrating from Helm chart to ECK operator (eck-stack helm chart version 0.12.1)  
**Fresh install or upgraded** : Migration from classic helm deployment to ECK

**Is there anything special in your setup?**  
Currently using classic helm deployment with following resources:

- clusterrole/clusterrolebinding
- configmap
- deployment
- service
- serviceaccount
- ingress
- hpa

Planning to migrate to ECK-managed APM Server using eck-apm-server CRD.

**Description of the problem including expected versus actual behavior:**  
Need clarification on which Kubernetes resources are automatically managed by the ECK operator versus which need manual management.

Current understanding is that ECK manages core resources through the CRD spec:

```yaml
eck-apm-server:
  spec:
    config: {...} # Replaces configmap
    podTemplate: {...} # Pod/deployment specs
    http: {...} # Service configuration

```

**Specific questions:**

1. Are RBAC resources (clusterrole/binding) automatically created and managed by the operator?
2. Is HPA configuration supported through the CRD spec or needs separate resource?
3. What resources still require manual creation/management?

**Steps to reproduce:**

1. Have classic APM Server helm deployment with all resources listed above
2. Migrating to ECK operator using eck-apm-server CRD
3. Need to understand which resources to keep/create manually vs let operator manage

Would appreciate clarification on the operator's scope of resource management to ensure proper migration. Thank you!
