Is there a preferred upgrade path / procedure for firmware? I seem to be having issues every time I upgrade, especially from anything in the 17.0/17.1 series to anything in the 17.5 series. The issues I have seen are:
- HA auxiliary upgrades and reboots, but HA primary fails to reboot and gets stuck on the previous version
- Upgrade appears to complete but HA is disabled after upgrade (a real pain if the unlicensed node is the one with all the config)
- Upgrade completes but both HA devices decide they are primary
- Upgrade completes but doesn't seem to work quite right until both HA devices are rebooted again
Under UTM9 I could reliably do a firmware upgrade pretty much whenever I wanted and there would only be a brief half second outage while the HA changeover happened. XG seems to be a lot more fragile.
I'm almost inclined to break HA, do the upgrade, then re-create HA, on the assumption that that might be more reliable. It's a heap more work though, and not without risk.
I haven't yet tried doing a pre-upgrade reboot of both nodes (some of the uptimes can get pretty big). Might that help?
Thanks
