Do the experiment.

I copy 32 bit cygwin between my desktop and laptop (Windows 7, 64
bit) (using a network drive as an intermediary) and it work fine for
me.  I use xcopy followed by a Windows mirroring utility (mirror -
<http://home.cs.tum.edu/~jain/>) in a cmd batch file.  For a first
install xcopy alone or a copy using Windows Explorer should work
fine.

This all assumes that that both installation are at equivalent
locations, e.g., C:\cygwin.  When I, on occasional, run it from
H:\cygwin, it runs but seems to have problems finding customizations.
I've never tried tracking it down but mounts set in fstab to C: are a
possible problem, as are lack of environmental variables set in
Windows.

Good luck,

- Barry
