I would like to upgrade the SG450 from 9.0 to 9.5. Please suggest the step for the upgrade that firmware.

- 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
