Instruction for migrating the configurations from deprecated stable/prometheus-operator to new repo

[Zhang Zhao]

Hi.. 

Anyone can guide me how to migrate all configurations of stable/prometheus-operator helm chart to the new  kube-prometheus-stack repo? I followed the “zero downtime” instruction in Github (https://github.com/prometheus-community/helm-charts/tree/main/charts/kube-prometheus-stack) by running command below. But it looks there are multiple steps missing in the doc.

helm upgrade --install test prometheus-community/kube-prometheus-stack --reuse-values --set nameOverride=prometheus-operator

The chart was migrated to "kube-prometheus-stack", however the pod for prometheus-operator kept crashing.
