Sophos SG450 How to Upgrade from 9.0 to 9.5

- Backup your configuration

- get iso of the version you want to install

- install iso on the SG

- restore your configuration

You could use alternative the Up2date function in your GUI, but this is a huge step, so I would prefer the new installation.

Best regards

The iso file can install via GUI right

Cannot install from tbe current UTM GUI, although the install does use a web  page.  You must boot from CD using an external CD drive.

He is right.  New install is hours faster and produces a configuration without uphrade baggage.
