Unfortunately it is not so nicely segmented, I started writing it 9
years ago before I was really aware of n-tier design. If I rewrote the
app I would like to use that type of design.

This app is really an in house app that is not owned by me but by the
certifying agency I work for.

We recently moved our web-site to a linux server. There are data driven
pages on the web site (www.star-k.org) which are coming from a mysql
database. Every night a program runs that creates xml files from vfp
data that are uploaded to the web server where a scipt is run to
overwrite the mysql database with the new data from the vfp database.
Can a VFP based add-on run on a linux server?

The agency that I work for does not have a big IT budget and I doubt
that I could even get that proposal out of my mouth without it being
denied.

Based on everyone's reponses I would be very leary of using .net. I am
not really ready to proceed right now with any upgrades. It is
something that I am thinking about. There is another IT person in my
office who very strongly wants to move to SQL sever and asp.net. He
does have experience with both but I am not sure that he realizes how
complex the current app is.
I really appreciate your thoughtful reply and all of the other great
help I get from this list.
