Here we cover how to upgrade to latest Longhorn from all previous releases.

Upgrading Longhorn

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

1. Upgrade Longhorn manager

2. Manually Upgrade Longhorn Engine

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

3. Automatically Upgrade Longhorn Engine

Since Longhorn v1.1.1, we provide an option to help you automatically upgrade engines

4. Automatically Migrate Recurring Jobs

With the introduction of the new label-driven Recurring Job feature, Longhorn has removed the RecurringJobs field in the Volume Spec and planned to deprecate RecurringJobs in the StorageClass.

During the upgrade, Longhorn will automatically:

  • Create new recurring job CRs from the recurringJobs field in Volume Spec and convert them to the volume labels.
  • Create new recurring job CRs from the recurringJobs in the StorageClass and convert them to the new recurringJobSelector parameter.

Visit Recurring Snapshots and Backups for more information about the new Recurring Job feature.
