Follow the installation guide to do a fresh install of v10:

{% content-ref url="/pages/-LO3GjKEAkMqMY1bCZl9" %}
[Install](/docs/install/install-on-linux.md)

Configure Bastion and use your old MongoDB URL from v8:

{% content-ref url="/pages/-LN49CDhxg0No7AtEi9S" %}
[Configure Bastion](/docs/configure/configure-bastion.md)
{% endcontent-ref %}

Run MongoDB migration for v10 inside the new `Bastion` directory:

```bash
npm run migrate
```

Publish Slash commands to Discord:

{% content-ref url="/pages/UJvidh1Eg20U8G8fhAVt" %}

{% endcontent-ref %}

Now you can run Bastion:

{% content-ref url="/pages/-LO3GjKZHxQFDMMECQ-k" %}

{% endcontent-ref %}
