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
helm chart 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.
Thanks
