On moving a device to a different upgrade channel, the device immediately updates to the software version in that channel.

If a channel has an updated software version, the devices in the channel updates to the latest software version during the regular maintenance window.

You can’t use the device when the upgrade is in progress. Don’t power down the device during the upgrade process. The device restarts during upgrade.

Here are the best practices for using the software upgrade channel:

• Ensure most devices are in the Stable channel. Stable channel is the default upgrade channel.

• Configure a minimum number of devices to use the Preview channel. This setting helps to evaluate the upcoming Stable software version for new or changed features, benefits for users, and analyze the impact on workflows.

  For example: You can configure the telecom support team or similar to use the Preview channel in your organization.

• Join the Webex Calling Beta program and set devices to use the Beta channel. This capability allows access to new features earlier than the Preview channel. Also, you can provide feedback towards the implementation of the new features. Install the Beta software on your regular device and continue with your tasks. Using this configuration you can confirm if the software works in your environment.

  If you’re part of the Beta program, then the Beta channel is available.

• Use the Stable-delay channel only if you experience an issue with the Stable channel. Ensure to open a support case with the Cisco support team, to investigate the issue. While the investigation is in progress, you can move all affected devices to the Stable-delay channel.

  You can’t use the stable-delay channel to delay upgrading the device software forever as the software in this channel is updated approximately every three months.

• The Test channel is available to use during a problem investigation, but administrators can’t configure this channel from the Control Hub. The Cisco support team may move a device to the Test channel, to investigate an issue that you report.

You can check the software version and the software upgrade channel that your device is currently on:

1. From the Control Hub, go to Devices. Select the device to inspect.

   • Software version indicates the software version that the device is currently running.

   • Software channel indicates the software upgrade channel that the device is configured to use.

2. Scroll to Device Management and click Device Settings, to change the Software upgrade channel.

   

3. Click the Software Upgrade Channel drop-down, to choose the required channel. Click Save. A success notification displays after the installation completes.
