Ahh… I understand your question now.
While I did not have any involvement in the creation of the hardware or software, I would hazard a guess that there is a chance of it not working as intended when doing a firmware upgrade on a production system.
In my experience, updating a system and then uploading the config is generally a way to make sure that the update process does not mess up the configuration.
Anyone with experience on this specific hardware/software package is more than welcome to explain.
