Which devices and versions are supported?
Since we periodically release updates and improvements to balenaOS (the host OS running on all balena devices), we encourage you to keep your devices up to date. We offer self-service host OS updates between 2.x versions, from 1.x to 2.x versions, and between 1.x versions.
Note: BalenaOS 1.x to 2.x updates limit the amount of data you can have in your application's
/data folder to about 170MB (compressed). If you have more data, the update will fail and your device won't be modified.
Supported device types:
- For the Raspberry Pi series, self-service updates are available from balenaOS versions 1.8.0 and upwards (including 2.x versions) to any versions after balenaOS 2.2.0.
- For BeagleBone devices, you can update balenaOS 1.8.0 through 1.26.0 to the transitional 1.30.1 version, and from 1.30.1 and upwards (including 2.x versions) to version 2.2.0 and newer.

For device types and balenaOS versions that are not yet supported, please contact us on the forums. We are continuously expanding the range of versions and types that can be updated.
Running an update
To run an update for an individual device, navigate to that device's Actions tab, click Update balenaOS, and select the version of balenaOS you would like to update to:
Updates can also be made to multiple devices in the same application. From the device list, click the checkbox to the left of any online devices you wish to update. Then click the Group Actions button in the upper-right corner of the dashboard, followed by Update balenaOS:
Note: Updates to the supervisor, balena's agent on the device, are handled in conjuction with host OS updates. If you need to update the supervisor separately from the host OS, please contact us for assistance.
After an update begins, the device summary page will show a progress bar that marks the steps completed for the update. Some steps that take longer, such as the device downloading the new OS image, may make the progress bar appear stuck. This doesn't mean anything has gone wrong with your update. We are working on making the update process more informative.
Update time can vary significantly, depending on the speed of your network, the speed of your SD card (or other storage medium), and your device performance.
If your balenaOS update fails for any reason, the device should still be recoverable. For devices running balenaOS 2.x, the user application should still be running normally, and the reasons for failure can be examined through the update logs at
/mnt/data/resinhup/. If you have any issues, please contact us on the troubleshooting section of the forums.
