We're currently running BMEE3.6 (only the RADIUS component) on a NW 6 sp2
server. The RADIUS.NLM running is v 3.2 (as reported via "modules
radius.nlm" on the server console)

Our plan is to implement two new servers with NW6.5, and they will take over
the RADIUS load from our server currently in place.
What product should I be researching for this upgrade? I've seen several
people mention NMAS?? While others mention BM3.8??
What is the difference, what versions should I look into, etc.... ??

Also, what impact will upgrading to a new version of RADIUS (whether NMAS or
BM) have on my existing implementation? In particular, my current DAS

thanks in advance,
