Node Upgrade Runtime Behaviour

The following describes the behavior of the Node Upgrade tool while performing routine upgrade tasks.

Note:  If the connection to the node is interrupted during the upgrade, the upgrade may be cancelled and will fail unless the upgrade was in the final stages and had no requirement for further interaction with Lighthouse. In this scenario Lighthouse may still report the node upgrade as failed if it was unable to confirm that the upgrade succeeded due to the node being disconnected during the validation period. Failure to upgrade one node does not affect other nodes in the upgrade job.
