iofogctl provides a means to upgrade your Agents to the latest version and rollback to the previous version following an upgrade.
To upgrade, run the following command:
iofogctl upgrade agent agent-1
The Agent will spend a few minutes upgrading at this point. If the version doesn't change (e.g. via
iofogctl get agents), then it is possible something went wrong. Review the contents of
/var/log/iofog-agent-upgrade.log to find the output of the upgrade process on the Agent.
To revert the upgrade, run the rollback command:
iofogctl rollback agent agent-1
