I have a customer who wants to move their FMSA 12 from Windows to MAC.
Will the Key Code they currently have still work after installing the MAC version.
Yes, it will. But your license agreement is not to use the license on both at the same time. You'll need to uninstall it from the Windows Machine and then you'll be good to go.
Don't forget to export schedules and groups! And document any other settings like email and folders, security, etc.... so you know what to put in the Mac server.
