Hello Team, need help/suggestions to migrate the Pubsub+ version without any downtime and data loss.

Currently running pubsub+ with HA on EKS cluster

pubsub+ 9.8.0.12  
[https://hub.docker.com/\_/solace-pubsub-standard?tab=description#:~:text=9.8.1.19-,9.8.0.12,-9.7.0.42](https://hub.docker.com/_/solace-pubsub-standard?tab=description#:~:text=9.8.1.19-,9.8.0.12,-9.7.0.42)

helm chart 2.1.1

> **[pubsubplus 2.1.1 · solace/solace](https://artifacthub.io/packages/helm/solace/pubsubplus/2.1.1)**
>
> Deploy a single-node non-HA Solace PubSub+ Event Broker Software onto a Kubernetes Cluster

I tried upgrading pubsub+ but the readiness check failed and found one discussion regarding that

> **[Issues with running Solace Helm chart with Redundancy and TLS enabled.](https://community.solace.com/discussion/1203)**

As per the discussion I need to migrate the helm chart first from 2.1.1 to the latest 3.0.0

But not able to do the in-place upgrade of the Pubsub+ helm chart

```javascript

Forbidden: updates to statefulset spec for fields other than 'replicas', 'template', and 'updateStrategy' are forbidden

```

so looking for a solution to migrate without any downtime and data loss.

Thanks
