>We are planning to rewrite a VFP application which uses DBFs to .NET and SQL Server. The system is extremely large and is comprised of a large number of subsystems invoked from a main PRG and menu. It is not considered feasible to convert everything at once. Instead the plan is to rewrite a piece at a time as resources and budget become available. Has anyone done something like this? To me it seems like the data is going to have to reside in both VFP and SQL Server until everything is converted. Any tips on good ways to do that?

Thanks for the advice. Most of that is not within my control. For at least a couple of reasons the decision was made (above my level) that we can only do it a piece at a time. I have been asked for advice on the data migration strategy so that is what I am concerned with.
