merge two independent 800xA systems
it is possible to merge two independent 800xA systems ? there is two 800xA systems with two different projects if there any changes/modification in system i have to go to different control rooms, if it is possible then i can change/modify programme from any one station by opening particular project.

800xA Multisystem Integration makes it possible to supervise and operate several 800xA systems from one central operating room. The 800xA subscriber and provider systems can be in the same Windows domain, different Windows domain, or different workgroups. The supervised system can be without any local workgroups or be a complete system with its own local operator room. The supervising system is called the Subscriber and the supervised system is called Provider. Two services implement the communication, the Remote Access Server running in the provider system, and the Remote Access Client running in the subscriber system.
I think there's some misunderstanding here about what MSI actually is.....
MSI allows one control room to supervise multiple systems. It does NOT join those separate systems together. You still need to engineer, maintain and backup those separate systems. You will still have to "go to different control rooms" to make changes. (Whether you physically walk to another control room or open a remote session using RDP is another matter entirely.)
If what you want is a single system that you engineer from one location, backup once and operate the entire plant with, then you need to explain why you have two systems in the first place. Presumably there is some operating requirement ? size isssue ? Networking problem ? location issues ?
If there is no valid reason that you need two systems, then yes you can "merge" them into one. But there is no automagical way to do this. It will take some engineeering time and a bunch of import / export files.
