Do you mean your application based on MS Access will be upgraded to MS Sql Server?
First, Oledb provider does support MS Sql Server. The Microsoft OLE DB Provider for SQL Server provides an OLE DB interface to Microsoft® SQL Server�2000 databases. Using the OLE DB Provider for SQL Server, SQL Server distributed queries can query data in remote instances of SQL Server.
