Many of our customers have a corporate IT initiative to move to Windows 7. In other cases they purchase new hardware and notice that Windows 7 is the only OS available. Cimplicity version 8.1 provides full support for Windows 7. Automatic configuration upgrades with Cimplicity are the best around. We've converted version 3 to version 8.1 with no manual touch ups.
Don't get caught with an old system that is not easily replaceable due to hardware availability. Older Cimplicity versions (4,5) typically run on Windows NT machines and versions 6 and 7 run on XP. Both these platforms are hard to find these days, so in the case of a hardware failure, buying a new PC and simply re-installing existing software may not be an option. The best option is to upgrade proactively now while the older system is still functioning and you can do a side by side migration.
