If the application uses different technologies such as ADO, RDO, DAO and custom data access, what’s the best way to go?
When your application uses different technologies, you should consolidate all of the data access into a single technology before beginning the upgrade. Your best option in this case is to use ADO because it can be upgraded automatically by the upgrade wizard. This in turn, will reduce the number of manual changes you will need to make in the upgraded code. As an alternative, you can choose to upgrade each technology separately. This requires that you create a new Visual Basic 6.0 project for each technology that your application uses. Each project must be upgraded separately. After all of the projects have been upgraded, you will have to integrate them into a single application in Visual Basic .NET.
