Can someone suggest the proper way to upgrade both the ASA and ASDM software on the Cisco ASA5505 at one time without getting into trouble like I just did?
Here's what happened. I copied the asa821-k8.bin and asdm-621.bin files to flash memory, then renamed the older versions as Oasa724-k8.bin and Oasdm-524.bin, and then issued the reload command from the Windows GUI.
Big Mistake, I lost ASDM connectivity entirely and was forced to buy a USB to serial port adapter cable and connect the CLI command port cable to it to be able to get back into the unit. I found that it was running the asa821-k8.bin kernel as expected, but apparently the ASDM was still running 5.24 version.
Should I just have created a new folder and moved the older versions to that folder, then issued the system reload command and hoped for the best?
I get the feeling that I fouled things up, I am guessing that I would have to use tftp to reload the boot image to get the ASA5505 back up again (using the ROMMON commands)
In fact the only way that I was able to recover the Windows GUI was using the boot command to the older asa724-k8.bin image.
What is the right way to upgrade to the newer versions asa 8.2(1) and asdm 6.2(1) ?
I really do NOT want to risk losing my ability to talk with this box and I spent an anxious afternoon yesterday, when I got the pop-up message box "cannot bring up asdm manager"
After working with the CLI port, I noticed that following error:
Device Manager image set, but unable to find disk0:/asdm-524.bin
*** Output from config line 75, "asdm image disk0:/asdm-5..."
So apparently some configuration file needs to point to the correct asdm, and just blindly changing the files in the folder will NOT work.
after more working with both the CLI port and the Windows GUI port, I found that the "asdm image" command was NOT working in the CLI software, but apparently was working in the GUI software, so I ran that command to tell the system to use the newer 6.21 on start up.
After this and issuing the reload command from the CLI I was able to come up successfully with the newer asa and asdm software.
I would say that having CLI access is invaluable in this case.
I am NOT sure why the "asdm image" command appears inaccessible on the CLI port.
As far as I am concerned this problem has been solved (using educated trial and error)
When the ASA boot it tries to use the "boot system" command file in the config. If it doesn't fine that file (it was not there because you renamed it) it boot the first image it will find..
Though for ASDM the ASA just uses the image that you have. You were pointing to asdm5.2 and renamed it, so there was no valied ASDM image to use.
In other words you should have just changed the "asdm image" and "boot system" commands in the config and point them to the new files, save the config and reboot and then it would have worked fine.
I hope it helps.
