Hi Stephane,
I've done a couple of conversions from 2.6 to client/server using VFP to Oracle and MS SQL Server. I used a framework to build the VFP interface. Using a framework gave me a big headstart in rebuilding all my data entry screens.
I use parametized views of tables that are constantly changing and I download static tables to VFP local lookup tables. This makes the interface very quick. Having local lookup tables, I was able to salvage a lot of the data validation code from 2.6. I didn't have to rewrite all that business logic in SQL stored procedures.
Also I download data to VFP temporary tables to do any complex calculations. Using the downloaded tables I found that I was able to salvage a great deal of my 2.6 code that handled business calculations and specialized reports.
I found that this combination of a framework for the interface and downloaded VFP tables to salvage some 2.6 code worked very well in migrating to a client/server environment.
Good luck,
Paul

We fist developped this app converting Fox 2.X App and choose this approach to avoid full rewrite of the biggest prgs (with no user interface)
