Is there a way to use existing volumes or volume claims?

[th0th]

Hi,

When deploying the helm chart, I want to use the existing persistent volumes. For example, if I want to delete and redeploy the chart, or restore from a backup, I will have to move the existing data from previous volumes to the newly created ones. I checked the values.yaml, but couldn't find a relevant configuration option, Is the chart configurable for such a case?
