OK, that said, the SQL Express version supports 10 GB of data, so it will depend on the size of the database if they need to purchase SQL Server.

Regarding migration, I would imagine that if the data structure stays mostly the same, it would not be a real big problem to convert existing clients.

So my conclusion is, check if old clients can use SQL Express with the 10 GB limit, and check if an automatic data conversion is possible. If both are possible, supporting VFP tables is not important and only creates additional work.
