Massive firmware update

[Sergio]

Good morning!

I would like to use GenieACS to update the firmware of a lot of CPEs.
I was thinking, first, to try to implement it via GenieACS-GUI, but I 
even don't know how to start. Maybe a selectizer in a new tab will fit, 
but I don't know, and I would need guidance.
The other way I was thinking of, it's via API. But I don't know if it 
would collapse or if it would be more difficult to accomplish.

Hope you could help me with your advice!

Thank you.

Sergio F.
