Bobbr,
Traditional thought would say that an "upgrade" is an improvement to the previous release. Since we are dealing with both software and hardware issues when we are discussing processor programming languages, the are numerous issues that are addressed in the upgrade from R7.0 -V9.0 to R7.0 - V14.2. SOme AVaya is willing to share with us having more to do with fixes with hardware conflicts, but I'm confident that there are additional "bug fixes" that are "resolved" in V14.2.
It does perform very well and we have done 100s of upgrades from R3.X to V14.2 without a hitch.
Let me know how we can help. Andrew Roach
