# Updating k3s
## Before you start!
Ensure you back up your k3s cluster. This is particularly important if you use
an external datastore or embedded Etcd. Please refer to the below guide to
backing up your k3s datastore:
https://rancher.com/docs/k3s/latest/en/backup-restore/
Also, check your volume backups are also working!
## Proceedure
### Updates using Ansible
To update via Ansible, set `k3s_release_version` to the target version you wish
to go to. For example, from your `v1.19.3+k3s1` playbook:
```yaml
---
# BEFORE
- name: Provision k3s cluster
hosts: k3s_cluster
roles:
- name: xanmanning.k3s
vars:
k3s_release_version: v1.19.3+k3s1
```
Updating to `v1.20.2+k3s1`:
```yaml
---
# AFTER
- name: Provision k3s cluster
hosts: k3s_cluster
roles:
- name: xanmanning.k3s
vars:
k3s_release_version: v1.20.2+k3s1
```
### Automatic updates
For automatic updates, consider installing Rancher's
[system-upgrade-controller](https://rancher.com/docs/k3s/latest/en/upgrades/automated/)
**Please note**, to be able to update using the system-upgrade-controller you
will need to set `k3s_install_hard_links` to `true`.
