Netsight 6.2 is not released yet - if you'd like to test the beta version you need to contact the GTAC to get access to the software.
The upgrade is pretty easy, copy the file on the Netsight server, change the file attribute to r/w with "chmod 777 filename" and start the file with ./filename
Grap a cup of coffee and wait till the uprgade is finsihed and you'd enjoy the endless potential of Netsight 6.2
