Re: Can you copy datafiles from one OS to another?

Unless the OS's are binary compatible, you cannot copy the files from one system to another. So in general you can't copy from one OS to another, and sometimes (depending on the changes at the OS level) you can't copy from one version of a particular OS to a newer version of the same OS.
