## Check for updates

Click **Check again** to refresh the available versions. The screenshot highlights this button. Version numbers are examples; yours will depend on the current release.

Before proceeding, read the release notes and [create a backup](https://usefiretower.com/docs/backups). Keep the matching root key and deployment configuration.

## 1\. Update the control plane

In **This Firetower**, click **Upgrade to…**. This opens the plan for the control plane.

Follow the run until it succeeds and the control plane is reachable again. Resolve a failed step before updating workers.

## 2\. Update the workers

Let running tasks finish, or stop them deliberately after saving their outputs. A worker update restarts its execution environment. Do not interrupt work you need to keep.

Select the machines to update, then click **Plan the update for…**. Workers are updated to the control-plane version.

Keep **Wait until nothing is running** selected. Click **Start the upgrade**; Firetower waits for the selected workers to become idle. If you choose not to wait, affected sessions will end.

In the desktop app, find **This app**. Click **Update to… and relaunch**. Save any unsent message first; the desktop window will restart.
