# 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"
```
