Hi Aidar, Upgrade should be easy enough however you can take following precautions, 1. Take backup of all the logs and delete them all from appliance. that will speed up the box to come back after reboot because all the logs are achieved before reboot. 2. Take system config, certificate etc backup just in case it does not come back after reboot. Lastly, have patience because it sometimes take 15-20 mins to come back after reboot. You can also refer the how-to guide for upgrade though upgrades are straight forward. Regards, Kapil
