# Step K: Start channels
<a name="upg-std-start"></a>

When all nodes have been upgrade, you can start the channels that were previously running.

**To start channels**

1. On the web interface for the primary Conductor Live node, access the **Channels** screen.

1. Toward the top of the page, select **Tasks** and **Start Channels**.

   Alternatively, if you want to start channels individually, select the play button on each channel that you're starting.

If you have only one Conductor Live, the upgrade process is complete when you start the channels. Otherwise, continue to the following section to enable high availability.
