# Upgrade

This document describes steps to upgrade your self-hosted <code class="expression">space.vars.product\_name</code> deployment.

To upgrade **all** regions of your <code class="expression">space.vars.product\_name</code> setup, run the following command:

{% tabs %}
{% tab title="Bash" %}

```bash
airctl upgrade --config /opt/pf9/airctl/conf/airctl-config.yaml
```

{% endtab %}
{% endtabs %}

To upgrade a specific region, run the following command, replacing with the name of the region you'd like to upgrade:

{% tabs %}
{% tab title="Bash" %}

```bash
airctl upgrade --region <region-name> --config /opt/pf9/airctl/conf/airctl-config.yaml
```

{% endtab %}
{% endtabs %}

Sample output of the upgrade command for a specific region:

{% tabs %}
{% tab title="Bash" %}

```bash
# airctl upgrade --region Region1 --config /opt/pf9/airctl/conf/airctl-config.yaml
 INFO  rollback state directory /tmp/airctl_ddu_backup_Region1_240020739

 SUCCESS  Upgrading region Region1                                                      
upgrade done
```

{% endtab %}
{% endtabs %}

#### Update PXC objects:

{% hint style="warning" %}
**Warning**

Running airctl upgrade from previous version (December release) to current version will not update the memory requests and limits for percona pxc-db statefulsets.
{% endhint %}

{% tabs %}
{% tab title="Bash" %}

```bash
kubectl patch pxc percona-db-pxc-db -n <namespace> --type='merge' -p '{"spec":{"pxc":{"resources":{"requests":{"memory":"3Gi"},"limits":{"memory":"6Gi"}}}}}'
```

{% endtab %}
{% endtabs %}

Once this command is run, statefulset *percona-db-pxc-db-pxc* for the respective namespace will get updated and new replicas will get created with updated memory requests and limits.
