# Upgrading Chart

### From v1.x to v2.x

Chart 1.x was under the assumption that all mounted volumes would be PVC's. Version > 2.x allows for more flexibility and will inject the yaml from podTemplate.volumes and podtemplate.volumeMounts directly.

v1.x
```
    volumes:
     - name: "yourvolume"
       path: "/yourpath"
```

v2.x
```
    volumes:
     - name: "yourvolume"
       persistentVolumeClaim:
         claimName: "yourvolume"
    volumeMounts:
     - name: "yourvolume"
       mountPath: "/yourpath"
```
