Minimal Effort Upgrade involves an outage window where you shut both members down, upgrade them, then bring them both online at the new version. The installation and upgrade guide has a few. You're limited to application features of the lowest version (so in my case, R80.20), but you can use OS-level features of the new version (such as the new kernel and userspace, new filesystem, etc.)Īs for question 2, that's roughly how most cluster upgrades go. For example, I have an R80.20 management server managing some R80.40 firewalls. With a jumbo HFA (patch bundle), management versions can also manage some newer firewall versions. I think R80.40 management can manage back to R77, which is something like eight years of backwards compatibility. All management versions can manage a few earlier firewall versions. For your first question, yes, R80.40 management can manage R80.30 firewalls, and the firewalls won't care.
