I have a pair PIX515-E with restricted license. I need to upgrade it to support active/standby. Can someone confirm if the part number i purchase below is correct?
For the first PIX, i purchase PIX-515-SW-R-UR (to upgrade from restricted to unrestricted)
For the 2nd PIX, do i purchase
PIX-515-SW-FO-R? This is the one i am not sure, is it correct?
