Multiple Updates needed in HA Setup SG450

Quick follow-up to a previous question - my HA setup is now licenced for another 12 months, so all good there.

But the Master SG450 shows that 4 Updates are needed. Currently its running 9.711 and has the 9.712, 9.7.713, 9.714 and 9.715 updates downloaded and ready to install. I am VERY WARY of the 9.712 update as that's the one that broke a lot of things back when it came out - including some HA setups. I dont want to break the environment this early on in the relationship ;)

Usually, I'd schedule each update for alte at night and let it install, reboot and then have the next one scheduled for either an hour later or the next night but that 9.712 update is making me nervous. Do you reckon it would be better to simply remote in late at night and just click the 'Update to Latest Version' button instead and apply ALL of the updates in one go then reboot and hopefully it all comes back up without breaking my HA setup?

Stupid HA, making me second guess myself ;)

Any tips or advice is appreciated ;)

  • Hello  ,

    Thank you for reaching out to the community, Updates in High Availability and Cluster Mode:

    In a high availability system there is an active and a passive node. When a new update is available, the passive node installs the most recent update and takes over the role of the active node. After that, the new passive node also starts the update process.

    In a cluster you have several nodes: Master, Slave and Worker. If an update is available, the slave node and half of the worker nodes install the recent update. When the installation is finished, the slave node gets the role of the master. Then the other nodes start the update process. Therefore you have no service disruption. If one or more nodes are in SYNCING state, you cannot update Sophos UTM.

    Thanks & Regards,
