# Update your Opal installation

> Learn how to update your self-hosted Opal installation.

New releases of Opal are made available on a regular basis—see the [changelog](/changelog) for details. To update your installation:

* Connect to your Opal on-premise dashboard: `https://<HOSTNAME>:8800`
* Click **Check for update**, which fetches the latest available version from Replicated
* Click **Deploy** to deploy, which automatically updates all necessary components

You can also go to the **Version History** in your on-prem dashboard, which has a list of all available versions. From there, you can roll back to previous versions.

Deploying a new release should take less than a minute and does not cause downtime. However, you should always monitor the upgrade in case issues arise.
