You can update your SmartServer IoT software to a newer release, if available, and you can re-image your SmartServer IoT with the same release that is already loaded on your SmartServer IoT to start over with a factory configuration.
If you need to revert your SmartServer to a previous release and you have a backup image of the system, you can follow the steps for Restoring the System or Database in the Backing Up, Restoring, and Cloning the SmartServer section to do so. If you do not have a backup image of your system, you need to perform a re-image of the system with the older software release as described in Updating with the SmartServer Console.
CAUTION: If you are using Internal Apps or services, verify that the files are stored somewhere under the /var/apollo directory (such as /var/apollo/data/apps) to make sure the files are preserved after a system upgrade. If you performed an upgrade and lost Internal Apps or services, follow the recovery procedure.
You can use any of the following methods to update or re-image your SmartServer:
The procedures described below are the typical methods for upgrading the SmartServer. These methods require access to the Internet. If you need to update your SmartServer and do not have Internet access, follow the procedure described in Updating over a LAN.
- Update using the SmartServer CMS as described in Updating with the SmartServer CMS.
This method is the easiest of the three methods if your SmartServer has an Internet connection. You download a small image loader to your computer, drag it to the SmartServer CMS, and click the Upload icon. An Internet connection is required, but a USB flash drive is not required.
- Update using the SmartServer Configuration page and a USB flash drive as described in Updating with the SmartServer Configuration Page.
This method is the easiest method if your SmartServer does not have an Internet connection. You download a SmartServer image using a computer with an Internet connection, copy the image to a USB flash drive, plug the USB flash drive into your SmartServer, and then start the update from the SmartServer Configuration page. Refer to the Configure Your SmartServer section for more information about the Configuration UI settings and functions.
- Update or re-image using the SmartServer console interface and a USB flash drive as described in Updating with the SmartServer Console.
This method is the easiest if you want to delete all of your data and re-image your SmartServer at the same time. You download a SmartServer image using a computer with an Internet connection, copy the image to a USB flash drive, plug the USB flash drive into your SmartServer, and then start the update or re-image from the SmartServer console interface.
