I'm upgrading my ASA 5520's firmware from 8.0.3 to 188.8.131.52 (not 8.0.5 yet) and I have upload this and the latest ASDM file 6.2.3. How do I tell the ASA to use the new firmware on next reload? I read that the ASA follows configuration order to know which image to boot, therefore you need to be sure the image you want to boot from is the first in order. What does that mean?
When you show the config, the boot commands will be listed like so..it will boot from the first one. Or simply remove the old image and it will boot from the new one, I usually leave at least 2 just in case.
