PIX image upgrade

Archived from groups: comp.security.firewalls (More info?)

It is fairly safe, not sure if you can copy the old flah image, never tried.
Copying the new one does a CRC type check to make sure it is OK, before
loading it into flash, so if it goes wrong you can try again. I have done
loads of these and all were without problems, so take a deep breath and go
for it :-)

You do not need to re-enter the key, all features will be there in the new
version.
