Yes, we can compare the outputs with the existing results of the "old" 
version.

The script I mentioned was the conversion script which is distributed 
with numpy (alter_code1.py).  But this script doesn't seem to be 
maintained any more.

I've tried with some sample scripts.  Simply replacing "Numeric" by 
"numpy" leads to other errors (wrong attributes etc.).  However since I 
don't have the resources to do this for the user, I've now installed the 
historical Numeric 24.2 and the user is warned, not to use Numeric for 
any new script and that Numeric will be removed in the future.  That 
should give him enough time to go through his old scripts and change them.
