Can I change VMS without losing the history?
The recorded history almost never converts from one system to another, and anybody who says otherwise without having tried it with those two particular versions is promising too much. Each platform keeps the video in its own format and with its own index database, and the conversion tools, where they exist, are partial.
What is done, and it is the usual thing, is to leave the old system running in read-only mode until its retention period runs out, while the new one records from day one. At the end of the retention period the old history no longer exists on its own and the old machine is switched off. It is the clean way, it costs one machine left running for a while, and it avoids conversions that almost always end badly.
What is worth migrating is everything else, and it is the part of the job that gets underestimated: the camera inventory with their names and locations, the users and their permissions, the maps, the rules and the schedules. Rewriting it by hand on the new system is what really takes time, and doing it badly is what makes people miss the old system even when the new one is better.

A written answer is enough to decide whether it interests you. To know whether it works at your site you have to see it on a real scene, with the image as it is and, on top of it, what the system understands from it. That is on the IRIS Neural website, which is the group's product.
