I have a PIX 515-E, running 7.1 code, that I need to upgrade to 7.2 code. The flash is not big enough to hold both images. So I have a few questions about the upgrade.
1) When I copy the new image over, does it automatically overwrite the existing one, or do I have to delete it first?
2) If it overwrites it, do I have to reboot at this point, or can I wait? In otherwords, will it continue to run although technically the original image has been deleted and the new one has not been initialized?
3) Do I have to specify the boot path on a PIX the same way I do on an ASA, or will it automatically boot to it when the firewall reboots?
