Here are the upgrade steps:
Download the asa software (asa803-k8.bin)from here:
http://www.cisco.com/cgi-bin/tablebuild.pl/asa
Download the TFTP server from here:
http://tftpd32.jounin.net/
-Unzip the TFTP server on a computer on the network
-copy the asa803-k8.bin file in the same extracted folder
-doubleclick on tftpd32.exe
-When you click on the 'show dir' button on the tftp server, the asa803-k8.bin file should be one of the listed files
-in the configuration terminal mode of the asa first ping the tftp server computer's ip address (you should be able to get ping responses)
-enter the command 'copy tftp flash'
-enter the ip address of the tftp server computer (press enter)and then enter asa803-k8.bin as the file name (press enter)
-it will ask you 'do you wish to proceed' - press 'y' for yes
-once you are back to the prompt issue the command
=======================================================
asa(config)# sh flash
Directory of flash:/
3 drw- 128 12:40:35 May 07 2006 asa803-k8.bin
7 -rw- 5539756 18:36:21 Jun 07 2006 asdm-521.bin
6 -rw- 1858 12:40:36 May 07 2006 downgrade.cfg
12 -rw- 8202240 18:29:04 Jun 07 2006 asa722-k8.bin
You would see asa803-k8.bin file in the list.
=======================================================
asa(config)# sh run boot
boot system flash:/asa802-k8.bin
This command tells us which file is in the boot system.
We need to change that to 803.bin.
That can be done by the command,
asa(config)#boot system flash:/asa803-k8.bin
========================================================
'reload' to reboot the asa so that the new software version takes affect
-when the asa boots up again, issue 'show version' command to confirm if the new software is now running on the asa.
DO rate helpful posts.
