I work for a reseller/MSS. Most of our customers are still running ver 4.1(5). One of our new customers has an NM-CIDS with IPS ver 5.0(2) already loaded. In the past we've just down graded the version. What are the differences in licensing/registration for the version 5 verses the version 4? I'd like to keep this customer on version 5, and start migrating other customers that direction. I'm just not real versed on the subscription, licensing, or registration issues for support and sig updates. Can anyone provide me some information or a good link to read about it?
