Got a PIX 515E firewall with an Unrestricted license. I want to upgrade it to 3DES encryption. I register for the upgrade on the Cisco web site, it recognizes the serial number, and I'm sent an activation key. However, when I go to enter that activation key, it tells me that it is going to DOWNGRADE the license to a Restricted license.
How do I get upgraded to 3DES without losing my Unrestricted license?
(BTW, this unit is not under warranty or support contract, so I cannot call Cisco for help. But since this is a freely available upgrade, I wouldn't think I should need to.)
