Per Cisco documentations
Upgrading Between Major Releases
To ensure that your configuration updates correctly, you must upgrade to each major release in turn. Therefore, to upgrade from Version 7.0 to Version 8.2, first upgrade from 7.0 to 7.1, then from 7.1 to 7.2, and finally from Version 7.2 to Version 8.2 (8.1 was only available on the ASA 5580).
Currently I have various Firewalls running and we would like to get everythign standard at 8.2.5.22
8.1.1-5580
8.0.3
8.2.2
8.2.4
8.2.3
7.2.3
8.0.2
The above documentation it says I need to upgrade to each major release. Yet the last line says one can go from 7.2 to 8.2 (in my case 8.2.5.22)
So I can skip 8.0. on the ASA that have 7.2 running?
also in some documentation the command copy tftp flash is used and in other copy tftp dir.
Which is best practice?
