Tell the ASA which software you want to run: If the ASA and ASDM software you just transferred to your ASA are the only copies in Flash, then the below steps aren’t completely necessary. Any time you have more than one copy in Flash, however, it’s a good idea to explicitly specify which software you want the ASA actually to run.

If you don’t specify, it will use the first version that it finds in Flash, which may — or may NOT — be the one you want it to.

Note: For good measure, let’s explicitly specify that we want to use the new versions we just copied onto Flash.

ciscoasa# configure terminal
 ciscoasa(config)# boot system flash:/asa825-k8.bin
 INFO: Converting flash:/asa825-k8.bin to disk0:/asa825-k8.bin
 ciscoasa(config)# asdm image flash:/asdm-645.bin

Note: At this point, the only thing that is left to do is to save your changes and reload your ASA so that it will boot into the new version of the software (and make use of the new version of ASDM).

ciscoasa(config)# end
ciscoasa# write memory
Cryptochecksum: aaaa08ce ccde38f2 19c42e08 dea24cbd
2713 bytes copied in 1.450 secs (2713 bytes/sec)
ciscoasa# reload
Proceed with reload? [confirm]

Once the ASA comes back up, verify that it did, in fact, boot from the new software.

ciscoasa# show version | include image
System image file is "disk0:/asa825-k8.bin"
ciscoasa# show asdm image
Device Manager image file, disk0:/
