Array of CString in VC++ 8?

If the code is well-written, it should be possible to just change the datatype in a few places and then fix the resulting compile errors. If it's *really* well-written, there won't even be too many compile errors.

However, the danger comes if the code is what I call "precarious". That's when any given change can produce unexpected differences in behavior elsewhere in the code. If this is precarious code, then (a) it will take more time to make the replacement, but (b) it's even more important that you *do* fix it, to avoid future problems.
