I have several apps that work with either DBF's or SQL Server.

The way I did it:
1. When you create your .dbf's, make sure the sturcture will work in SQL Server too. (For example, no date fields, no time fields, use only datetime fields)
2. Make another DBC and put nothing but remote views in it to connect to your DBF's. You'll want to use remote views for your entire application.
3. Upsize your dbf's to SQL Server. (If you designed them correctly, NO structure changes will need to be made).
4. Now, if you want to use SQL Server instead of DBF's, all you have to do is change the connection string in the .dbc with the remote views to point to the SQL Server instead of the .dbc with the tables in it.

This is really a pretty cool way to do it. To change from DBF's to SQL Server you dont even have to recompile.
