Upgrading ASA 5500 series 8.4

Detailed Steps

---

Step 1 Back up your configuration file. To print the configuration to the terminal, enter the following command:

hostname# show running-config

---

Note If you are upgrading from a pre-8.3 version, then the running configuration is backed up automatically.

---

For other methods of backing up, see the "Managing Software and Configurations" chapter in Cisco ASA 5500 Series Configuration Guide using the CLI.

Step 2 Install the new images using TFTP. Enter this command separately for the OS image and the ASDM image:

hostname# copy tftp://server[/path]/filename {disk0:/ | disk1:/}[path/]filename

For example:

hostname# copy tftp://10.1.1.1/asa840-4-k8.bin disk0:/asa841-k8.bin

...

hostname# copy tftp://10.1.1.1/asdm-64099.bin disk0:/asdm-641.bin

If your ASA does not have enough memory to hold two images, overwrite the old image with the new one by specifying the same destination filename as the existing image.

Step 3 To change the OS boot image to the new image name, enter the following commands:

hostname(config)# clear configure boot

hostname(config)# boot system {disk0:/ | disk1:/}[path/]new_filename

For example:

hostname(config)# clear configure boot

hostname(config)# boot system disk0:/asa841-k8.bin

Step 4 To configure the ASDM image to the new image name, enter the following command:

hostname(config)# asdm image {disk0:/ | disk1:/}[path/]new_filename

Step 5 To save the configuration and reload, enter the following commands:

hostname(config)# write memory

hostname(config)# reload
