Software Updates
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 or 3.16.11. For specific upgrade paths, see Upgrade Paths.
You have several options to upgrade Litmus Edge. If you need to download an updated version of Litmus Edge, visit Central Portal.
The upgrade process preserves your data and existing configurations. After the Litmus Edge software has been installed on a device, this upgrade process can be used throughout the lifetime of the device.
Important
- You can't downgrade to a lower version.
- If needed, you can upgrade to the same version you're currently on. 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.
- An upgrade to an internal prerelease version is possible, but contains a warning. Prerelease versions are not upgradeable.
- Creating a backup prior to upgrading is recommended.
- You cannot upgrade if your controller is IDE. You must have a SATA controller to upgrade.
- If you want the same edge device configuration and setup on a fresh installation or with an update, you can use a template. See Templates for more information.
Caution: Software upgrades haven’t been validated yet on VirtualBox 6.1.x. An upgrade on VirtualBox 6.1.x may result in a corrupted and unrecoverable Litmus Edge instance.
