1. Load the image asa847-30-k8.bin from Cisco.com.
2. Read the release notes if there are additional steps needed after upgrade (which depends on the 8.4 version you are running at the moment).
3. If needed, delete old files from flash to make room for the new image.
4. In ASDM, go to Tools -> Software Upgrade from local Computer.
5. Choose ASA, your downloaded file and load the image to the ASA.
6. When asked, confirm to set the new image as the boot-image.
7. Reload
8. Test all functionality and correct problems if they show up.
