Upgrade pubsub+ version from to latest version

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+ https://hub.docker.com/layers/solace/solace-pubsub-standard/

helm chart 2.1.1 https://artifacthub.io/packages/helm/solace/pubsubplus/2.1.1

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

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

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.
