I read the doc on upgrading a Balance 20 from firmware 5 to 6 here
and had a question.
Its not clear if the unlock key is needed before the system reboots into v6 or afterwards.
If they key is entered after rebooting (while v6 is running), what state is the router in before they unlock key is entered? Specifically, I need to know if the admin web UI will be available remotely so that I can enter the unlock key.
