Create a backup before upgrading. Downgrades are not supported, so a backup is your only recovery option if something goes wrong.

Follow these steps to upgrade your PMM Server while preserving your monitoring data and settings. You can restore from your backup if needed.

Upgrade PMM:

helm upgrade pmm -f values.yaml --set podSecurityContext.runAsGroup=null --set podSecurityContext.fsGroup=null percona/pmm

After the upgrade, verify that PMM Server is running correctly and all your data is accessible:
```
kubectl get pods | grep pmm-server
```
Check the logs for any errors:
```
kubectl logs deployment/pmm-server
```
