 ### Upgrade Check Events
 Longhorn performs a pre-upgrade check when upgrading with Helm or Rancher App Marketplace.  If a check fails, the upgrade will stop and the reason for the check's failure will be recorded in an event.  For more detail, see [Upgrading Longhorn Manager](../deploy/upgrade/longhorn-manager).
