Firmware update
Read the notes to upgrading in the Release Notes!!
The steps should be the same for nearly every new firmware, but to be sure check the Release Notes.
Backup your configuration file
Copy the new version to the flash of the firewall.
ciscoasa(config)# copy tftp: flash: Address or name of remote host []? 192.168.1.12 Source filename []? asa804-k8.bin Destination filename [asa804-k8.bin]? Accessing tftp://192.168.1.12/asa804-k8.bin... !!!!![...]!!!!! Writing file disk0:/asa804-k8.bin... !!!!![...]!!!!! 14137344 bytes copied in 180.150 secs (78540 bytes/sec)
and now you have to install the asdm
ciscoasa(config)# copy tftp: flash: Address or name of remote host [192.168.1.12]? Source filename [asa804-k8.bin]? asdm-613.bin Destination filename [asdm-613.bin]? Accessing tftp://192.168.1.12/asdm-613.bin... !!!!![...]!!!!! Writing file disk0:/asdm-613.bin... !!!!![...]!!!!! 7562988 bytes copied in 96.390 secs (78781 bytes/sec)
control the files
ciscoasa(config)# show flash: Initializing disk0: cache, please wait....Done. -#- --length-- -----date/time------ path - 8386560 Jan 01 2003 00:07:24 asa723-k8.bin - 4181246 Jan 01 2003 00:08:28 securedesktop-asa-3.2.1.103-k9.pkg - 398305 Jan 01 2003 00:08:44 sslclient-win-1.1.0.154.pkg - 0 May 13 2008 16:28:36 crypto_archive - 6287244 May 13 2008 16:31:42 asdm-523.bin - 14137344 Sep 03 2008 03:31:10 asa804-k8.bin - 7562988 Sep 03 2008 03:35:38 asdm-613.bin - bytes available (41033728 bytes used)
