Overview

This site describes the Great Migrations Methodology for upgrading VB6/ASP/COM applications to the .NET platform.  It is also a user guide for the Great Migrations Studio (gmStudio), the software platform supporting this Tool-Assisted Rewrite methodology. 

Intended Audience

This document is written for individuals who will be in the role of Migration Lead in a project to rewrite a VB6/ASP/COM system for the .NET platform. This role is responsible for ongoing operation and configuration of gmStudio to facilitate the tool-assisted rewrite of a legacy VB6/COM/ASP application (or suite of applications). The ideal Migration Lead will have experience with the legacy application and a working knowledge of .NET.
