Default [Q] Moto X - ATT unlocked (no rooted) update

Hi to all
Got an Moto X - ATT unlocked (no rooted) in the USA.
It works great here in Peru (SouthAmerica), with a GSM carrier.
Some days ago, the phone is asking me for an update (4.4.2).
The question is:
Will be safe update the phone?. I'm not in the USA
Thanks in advance.

EDIT: it's ok. I update OK. no problem.
