Upgrade PX-Central on-premises

If you’ve installed PX-Central using Helm, you can use Helm to upgrade it as well.

Prerequisites

PX-Central must already be installed.

Upgrade

Use the following kubectl delete job command to delete the post-install job:
```
kubectl delete job -npx-backup pxcentral-post-install-hook
```

Upgrade the chart to the latest version. Enter the helm upgrade command, using the --set flag to specify any custom values you used during install:

helm upgrade px-backup portworx/px-backup --namespace px-backup --set persistentStorage.storageClassName=<STORAGE-CLASS-NAME>,pxbackup.orgName=<PX-BACKUP-ORG-NAME>
