Cisco ASA Upgrade: Pre-8.3 to 8.3 Upgrade Process Steps

I went onsite today to do an upgrade of an ASA that was on version 8.2(1).  I wanted to get them to the latest version, which at this point is 8.4(3).  With that said, this is one of the pre-8.3 to post-8.3 upgrades, which means taking proper precautions. 

First and foremost, the release notes specifically say to run the command: no nat-control.  Apparently, this can cause you problems if you dont, so make sure you run it.  Next, I did the upgrade to 8.3.  Make sure you are running a minimum of 8.2 code.  If you are running an earlier version, you will have problems.  See below what the upgrade looks like:

REAL IP MIGRATION: WARNING
In this version access-lists used in 'access-group', 'class-map',
'dynamic-filter classify-list', 'aaa match' will be migrated from
using IP address/ports as seen on interface, to their real values.
If an access-list used by these features is shared with per-user ACL
then the original access-list has to be recreated.
INFO: Note that identical IP addresses or overlapping IP ranges on
different interfaces are not detectable by automated Real IP migration.
If your deployment contains such scenarios, please verify your migrated
configuration is appropriate for those overlapping addresses/ranges.
Please also refer to the ASA 8.3 migration guide for a complete
explanation of the automated migration process.
