Difference in the amount of EWIs with the VB6 AI Migrator and Visual Studio Upgrade Wizard

Subject

Errors, Warnings and Issues (EWIs)

Applies to

VB6 AI Migrator Enterprise Edition, VB6 AI Migrator Developer Edition

Inquiry Description

I am getting many more EWIs with the VB6 AI Migrator than with the Visual Studio Upgrade Wizard, does this means that the Upgrade Wizard is converting more code than the VB6 AI Migrator?

Troubleshooting/solution

First, it must be stated that the amount of generated EWIs (Errors Warnings and Issues) is not (inversely) proportional to the actual quality of the upgrade process. There is a mechanism to provide a better quality conversion process and help the user to understand the upgrade process details.

It is recommended to compare the output source code from different upgrade processes to get a better idea of the generated code quality.

The EWIs evolve from one version to another in several ways:

1. Code conversion improvements: some EWIs get removed or modified because the automatic conversion is enhanced.
2. Conversion feedback improvements: other EWIs might be added to increase the feedback quality about already existing conversions.
3. Mixed improvements: a combination of the cases above.
