Updating asa software
Now it’s the time to upload the new software image file to the disk system of the firewall. ASA5505# conf t ASA5505(config)# boot system disk0:/asa802-k8ASA5505(config)# wr mem Reboot the firewall in order to load the new software image file. If everything works ok with the new image, you can delete the old one from disk0.
Cisco Adaptive Security Appliance Software Version 7.0(6) Device Manager Version 5.0(6) ASA5510# dir Directory of disk0:/ 5 -rw- 5474304 Jan 01 2003 asa706-k8675 -rw- 5823980 Nov 07 2006 asdm506255426560 bytes total (244064256 bytes free) ASA5510# 3. Here's an example: Address or name of remote host ? In fact, if you reboot your ASA without upgrading the ASDM, you may not be able to use ASDM after it reboots.
Also, the GUI device manager version (ASDM) is 5.2(3). Assume that our internal network range is 192.168.1.0/24. 192.168.1.10 Also, save the current running configuration.
Configure a TFTP server (you can use the free tftpd32) on an internal PC (e.g 192.168.1.10) and backup the current running software image from the firewall to your TFTP PC. Just issue the show run command and copy all configuration output from your terminal window into a text file. (truncated) 14524416 bytes copied in 118.210 secs (123088 bytes/sec) Since now we will have two image files on the firewall disk (old 7.2 and new 8.0 image files), we need to tell the firewall explicitly which image file to use when booting.
ASA5505# copy tftp disk0 Address or name of remote host ?
Important: Even though below steps are common to upgrade any version of Cisco ASA IOS and ASDM, you need to verify in website to understand the vendor recommended upgrade path.
