well i would like to say "it should work". I have been installing Orion a very long time and have had every type of experience in doing so...
Would like to hear about your experience with this install.
Best of Luck
I just went through the exact same thing you are about to begin. I decided to go for it and load the new version release and essentially start from scratch. This really wasn't a big deal since we had only been running previously for about 7 months. I had NPM and NTA to setup, but no additional pollers. So far so good a little over a month later. My network is not connected to the web, so the biggest challenge outside of getting all of the subnets into Network Sonar Discovery was getting the licensing taken care of. Good Luck, let us know how it goes.
