Software Updates
The upgrade process preserves your data and existing configurations. However, we recommend that you create a backup. After you install Litmus Edge software on a device, you can use this upgrade process throughout the lifetime of your device.
You have several options to upgrade Litmus Edge. If you need to download an updated version of Litmus Edge, visit Central Portal.
Important: For a seamless upgrade experience, you must follow the correct upgrade path. Skipping a significant LTS version may cause issues with the upgrade process.
When you upgrade, you must upgrade to version 3.16.10, 3.16.11, or 4.0.15. For specific upgrade paths, see Upgrade Paths.
Important
Before you upgrade, note that you can:
- Upgrade to an internal prerelease version. However, if you do so remember that you will not be able to upgrade again from that prerelease version.
- Upgrade to the same version you're currently on, if needed. For example, if your current version is 3.3.1, you can upload the 3.3.1 UPD file again to your Litmus Edge instance.
- Use a template to apply configuration and setup settings from an existing edge device to a fresh installation or to update another device. See Templates for more information.
You cannot:
- Downgrade to a lower version.
- Upgrade if your controller is IDE. You must have a SATA controller to upgrade.
Caution: Software upgrades on unvalidated VirtualBox versions may result in a corrupted and unrecoverable Litmus Edge instance. Litmus Edge supports Oracle VirtualBox versions up to version 7.2.0.
