one of our nodes in a HA cluster failed. The cluster is/was running on firmware 9.706-9.Found this KB Article regarding the replacement: https://support.sophos.com/support/s/article/KB-000035374?language=en_USThis describes what I need to do:5. Restoring HA after receiving an RMA'd device.
Syncing should now begin with the connected appliances.Isn't it necesarry to put the same firmware on the replaced firewall first?Besides doing a backup is there anything not described that needs to be taken care of? For example regarding licensing ...As far as I can see there will be no switch during the process. Is that right (would probably kick out a lot of remote users which I want to prevent; failover test will be done during a time when there is much less traffic).Regards,BeEf
licence is included within backup.
I install the same Firmware and make a factory-reset at the new device before rebuilding the cluster.
I connect initially eth3 only. ETH3 is preconfigured for HA…
Thanks to everybody. The replacement worked well with the instructions 5. Restoring HA after receiving an RMA'd device - surprisingly even with a different 9.7 firmware on the replacement.
