Modernize Online Cemetery Interment VB Application

I have a fully-functioning cemetery interment web application that was last compiled in Visual Studio 2011 (VB). All source files are on hand, including the Microsoft-based database that stores names and grid coordinates, although I may still need help locating that exact file...
