As Edgars already mentioned:
So if you have a really large amount of trends, upgrade will take a significant amount of time. After this it's not possible to go back to old firmware directly. You can do a recovery + restore if you have a backup from an old version. Otherwise there's no backward compatibility.
Quote:Upgrade might take some time if you have many trend logs, during upgrade red/green LEDs will toggle.
