Hi all! I have what might be a noob question, but more importantly a paranoia question. I read the following blurb in Cisco's documentation about upgrading the IOS on the ASA's:
ASDM does not work if you upgrade (or downgrade) the security appliance software from 7.0 to 7.2 directly or upgrade (or downgrade) the ASDM software from 5.0 to 5.2 directly. You need to do it in incremental order.
Example: In order to perform the ASDM software upgrade from 5.0 to 5.2, first upgrade from 5.0 to 5.1 and then upgrade from 5.1 to 5.2. Likewise, for the security appliance, first upgrade from 7.0 to 7.1 and then upgrade from 7.1 to 7.2.
The reason that this particular blurb concerns me is because we are running IOS version 7.0.2. (I know, it's as old as the ASA series, but I just picked up managing the device)
So, my real question is: Will I have to upgrade to 7.1, then 7.2, then 7.3, etc, etc, etc, until I reach the revision that we want running (8.4.2) in order for the device to continue to function properly?
Thanks for the help in advance!
