I have 2 Cisco PIX 525 units. Both configured identically. One was purchased new with Unlimited License. The other one was bought second hand, and reports as unlimited license, however, when I called cisco, the serial number was supposed to be a FO license.
Here's where I'm headed. I actually want to use the second unit as a FO unit to the first. How do I go about downgrading the license back to FO status. Second, if this isn't easily possible, can the unit be used as FO as is?
