zyxel usg20-vpn firmware upgrade path
Hello, I want to ask if there is the best path to upgrade, or can I upgrade directly?
My current version is 4.16 and I need to upgrade to 5.36
I tried to upgrade directly, but my original account and password could not be entered
Can't get in even with the default account and password
I would like to ask everyone who has encountered upgrade problems, thank you

Hi @rv3452
If the original firmware version 4.16 is official version 4.16(ABAQ.0)C0, it can be upgraded directly to 5.36(ABAQ.1)C0. We suggest you save the startup-config.conf before performing firmware upgrade.
If you lost the login username and password, follow this guide to backup the configuration file.
