I have ASA5540 with 1000 SSL-VPN License, then I would like upgrade from 1000 to 2000. Which part I have to add between
SSL-VPN licenses are not additive. So if you want to move up from a 1000 user license, the next tier is 2500 users. The second SKU above is the correct part to order in that case.
The first SKU is for 1000 users only (base AnyConnect Premium license for 1000 users). The third SKU is another way of packaging the same thing as the first one.
