Examine Key Files
The scripts used during the upgrade are designed to back up the key files most likely
to be found on the DNCS. Some sites, however, include special key files that are
unique to that site, only. As part of the backup, the upgrade scripts ask if you have
any special files that you want to add to the list of files to be backed up. When you
answer yes, the system offers you an opportunity to type in the directory path and
name of any special files you want to back up.
Important: You can save a lot of time if you spend a few minutes identifying those
special files now. Work with the system operator to determine if there are any
special files or scripts that need to be backed up.

following guidelines when you create the list:
Write down the home directories of all user accounts.
Note: These directories are typically found in the /export/home directory. The
upgrade scripts do not automatically back up or restore user-configured
accounts. All user-configured home directories must be specified as a key file to
be backed up in order to be properly restored after the upgrade.
Important: Be sure that you include the home directories off all users that have
been created.

Review all system cron files and write down any special cron files that you want
to retain after the upgrade.

Some of your special cron files may reference custom scripts. Be certain to
include those custom scripts on any list of special cron files you want backed
up.

Call Cisco Services if you are unsure of what cron files you need to back up
separately.
