Version 9.406-3 upgrade

DrMeskon

Hi,

we have Sophos SG330 with High Availability.

Current firmware version: 9.404-5
Latest available firmware version: 9.406-3

When upgrading to latest version should I first upgrade to 9.405-5?

Should I remove the HA if i want upgrade to check on one appliance? If i remove HA, the slave will perform factory reset and shutdown. Then I can upgrade master. But after upgrade what are procedures to bring slave back to production?

    If you upgrade to latest the appliance will automatically also install the updates in between the current one and the latest one.

    You can setup to reserve a node when doing an upgrade. The slave will then NOT update automatically and stay on the previous version. You can then after testing also update the slave manually.

    Be aware though that any configuration changes you make before you update the slave will not be applied to the slave so if you need to revert back then you may have to make those changes again.

    So if i will click update to the latest version it will update the production (master) appliance and slave leaves in previous version? But the reboot is required after update, so in a reboot slave kicks in and after master reboots with new firmware it takes over again? Is there a way to update just a slave so to avoid two failovers?
