ASP in VBScript for UI
C++ COM for BLL
ADO 2.8 and _conneced_ RecordSet objects for DAL
SQL 2005 for Data Storage
to:
ASP.NET 2.0 for UICOM Interop to connect to the C++/COM objects for BLL (and some pure .NET code where no COM existed in the past, using Ent Library)
ADO 2.8 under the COM objects like beforeSQL 2005 for Data Storage as beforeCOM and ADO Details

Problems
