Upgrade pubsub+ version from 18.104.22.168 to latest version 10.4.1.69
Hello Team, need help/suggestions to migrate the Pubsub+ version without any downtime and data loss.
Currently running pubsub+ with HA on EKS cluster
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.
