Hi guys

I got a question about a step that I need to do before I upgrade the MARS (I'm going to upgrade from 6.0.8 to 6.1.5)

•          Step 2 - Run the “pnexp” command to prepare & export a backup to an NFS or SFTP remote server.  You can export just the MARS config, just data, or both.  See below for link to syntax help.

As I understand I need to run this command (pnexp) to made a backup of the MARS so that's mean that after the upgrade I'm going to lose all the configuration that I had before or it's just to prevent in case that something goes wrong and maybe I need to made a re-image of the device.

Regards
