Upgrade an Agent from the host

Upgrading BlastShield™ Agents

We recommend that you keep all nodes In a BlastShield™ Network on the same firmware release.

Agents may be upgraded in two ways:

  1. The Agent may be upgraded directly from the Orchestrator. This is the most convenient method, but requires both the Orchestrator and Agent to already be on releases of 1.2 or higher.

  2. The Agent may be upgraded from the host on which it is running. (This works for all releases, but requires access to the host),

To learn how to upgrade the Agent from its host, read the steps below.

If you want to upgrade your Agent from the Orchestrator, read this article: Upgrade the Agent from the Orchestrator
