I hear what you are asking and I wish that it was easier to upsize but unfortunately it isn't.

Changing from VFP data to any other backend has many issues involved and only one of them has to do with accessing the data. We can USE a VFP table and then just jump around in the table to find the records we want, but when using a backend server we have to fetch a subset of records that is intelligently selected or else we suffer from horrible performance problems. It isn't very smart to SELECT * From Customer when the customer table in SQL server has 2 billion rows in it.

Since there is so much that has to be adjusted to deal with client-server databases it just doesn't make sense to try to develop an automatic magic upsizer thingie because it wouldn't handle much of the stuff that needs to be adressed .
