I don't think that will renew your current NS160 certificate, b'cos NS160 & NS302 are two different skill set certification, one is under 'Data' path and the other under 'Cloud', two separate paths. I think someone from certfication can confirm this.
Thanks for your reply! I imagined that it was like that! ... I wanted to take the opportunity to become certified in the cloud, but well, I will have to study to follow the same path. I think I will prepare the NS0-509 certification. (which in my case, won't make much sense).
