HollaEx Kit provides a straightforward way to upgrade the PostgreSQL database to the latest version. Running a simple command will allow you to upgrade your DB to a newer version with improved security and performance. It is always a good practice to keep your DB up-to-date.

## How-to

{% hint style="info" %}
The database upgrade command is supported by HollaEx CLI v2.8.1+
{% endhint %}

{% hint style="success" %}
The latest confirmed PSQL DB version is **14**.
{% endhint %}

```
hollaex toolbox --upgrade-psql-db-version 14
```

The command above will upgrade your local PSQL DB to v14 while automatically migrating all the DB data.\
Please keep in mind that the exchange will get restarted while the DB is getting upgraded.
