Live Security for an ancient XTM 25
An infrequent client has an XTM 25 running Fireware 11.7.3 and he inquired about Live Security. I thought the box HAD to be EOL by now, but to my surprise, it is still good until 01 Jul 2021.
So, my question is, if he buys LS for a year, can he simply add the new feature key and then upgrade to Fireware v12.1.3 Update 3 (for XTM appliances), or does he need some interim license, reactivation, or ???
He buys his own old boxes and has me do an occasional tweak to his configs.
