Thanks for the info,
I've been mulling this over, while I would love to time is short for me.
It seems that the NetSight 6.3.0.174 does support the C35's, so I may need to migrate to the new C35's then work on the Netsight upgrades over the semester.
The most pressing need is to install new AP's before school starts. That means the C35's have to be done sooner and if I can avoid the NetSight upgrades then it might be the easiest path.
Release notes for NetSight 6.3.0.174 indicate at least to me that they support the C35 controllers.
