Should – I believe so.
Will – hard to say, I hope you know the problem well or have someone who does, in case of any problems.
It really depends on a lot of things, like what versions of the two flavours of FoxPro you are using. Do you really find it necessary to have the application running on a Windows box, or can you just link to it from the Windows box and leave the UNIX one alone?
(btw not to nitpick or anything, but UNIX, unlike Windows, is an acronym).
