Yes, you can purchase a licence upgrade from FO to
o Restricted PIX-515-SW-FO-R=
o Unrestricted PIX-515-SW-FO-UR=
o Active/Active PIX-515-SW-FO-AA=
Just google the part numbers for an indicative price.
The last time I did this I ordered through a Cisco Business Partner and revieved a paper licence. I then had to register the serial number with a Cisco web site. The site issues a new licenece key which I entered and after a reboot had the new licence.
One minor issue, Cisco don't seem to keep track of such upgrades with regard to maintenance, i.e. an upgraded device still apears with the original model number on the maintenance.
