Asking for opinions concerning Informix vs AIM* Historian on 50-series: Having AP20's through 51D's, we have always been using the Informix Historian. We use it for trending (legacy Display Manager) and for reporting (via reduction groups). Since this Informix Historian is also available at ver. 7 for the AW-51F we are planning to buy, is there a really good reason to switch to the AIM* Historian? The cost to us would be learning new software and having the custom report package interface re-written. The only advantage to us that I know of would be that AIM allows changes while still running.
