v16.05.9 CMR-8 how to upgrade

Hello chong lim,

Thank you for reaching out to the community, following is the upgrade path:

================
v16.05 has declared EoL

Would request you re-image the appliance to the latest firmware:https://support.sophos.com/support/s/article/KB-000036812?language=en_US
-------------
You can download the ISO from: https://download.sophos.com/network/SophosFirewall/installers/index.html

Hi,

i don’t think re-image is an option because he cannot perform a restore.

Yup, he will loose the config !!
And step by step upgrade can cause either way config disruption not that he has a valid support. If he was on v17.5 still be considered and v18.06 is the right choice to migrate !! 
v16 I do not see any hopes at all

hi,

is there another way beside the re-image method?

i read somewhere that there is upload and boot method? but i cannot seem to find it again.

best regards

You can find it here - Move to a different firmware version: https://docs.sophos.com/nsg/sophos-firewall/18.5/Help/en-us/webhelp/onlinehelp/AdministratorHelp/BackupAndFirmware/Firmware/FirmwareMoveToDifferentVersion/index.html

If you get the installers, you could upgrade to 17.0 and afterwards to 17.5. I don't know, whether a direct upgrade to 17.5 was supported nor can I find any informations about this anymore.

Once you are on 17.5, you need to install at least 17.5 MR-14 - then you are able to perform an upgrade to the latest 19.0 firmware.

If you have an active support subscription: Maybe Sophos Support is able to support you with this - or at least able to get you the old update files. But I am not sure about this.

This also might help you: Upgrade SFOS 16.05.3 MR-3 to SFOS 18.5.3 MR3-Build408 or SFOS 19.0.0 GA-Build317 - Discussions - Sophos Firewall - Sophos Community

You are referring to a manual update process - which is technical correct. You can upload firmware updates and reboot the firewall. But you will need the update files for this - and I am not sure, whether they are still available.
