# Upgrade ISD-Argo with Argo CD and Argo Rollouts from v4.1.2 to v4.1.3

Please follow these instructions if you are upgrading from v4.1.2 (to 4.1.3).

{% hint style="warning" %}
**WARNING**: Please backup all the databases, in particular the Postgres DB, BEFORE beginning the upgrade. Backup procedures may differ depending on your usage of external DBs for Autopilot Services.
{% endhint %}

{% hint style="info" %}
**NOTE**: There are no DB changes from v4.1.2 to v4.1.3 so you need to only upgrade the helm chart.
