You can install NumPy and Numeric side-by-side just fine.  They use 
different name spaces.

In order to install new and old scipy you will definitely need to 
install one of them to another location besides site-packages (probably 
new scipy). 

Then you will need to make sure your sys.path is set up properly to find 
the scipy you are interested in using for that session.    In principle 
new scipy is almost identical to old scipy except internally it uses 
NumPy instead of Numeric.

So, once you convert from Numeric to NumPy, converting to the new scipy 
is done (it depends on if you regularly imported scipy_base or  
scipy_distutils.  If you did those are gone.  scipy_base--->numpy  and 

Keep us posted as to the difficulties as they arise...
