Upgrading Longhorn

There are normally two steps in the upgrade process: first upgrade Longhorn manager to the latest version, then upgrade the Longhorn engine to the latest version using the latest Longhorn manager.

1. Upgrade Longhorn manager

To upgrade from v1.0.x, see this section.

2. Upgrade Longhorn Engine

After Longhorn Manager is upgraded, Longhorn Engine also needs to be upgraded using the Longhorn UI.
