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.
When comparing the Upgrade Wizard and VB6 AI Migrator EWIs, the following comments can be made:
The EWIs present in the Upgrade Wizard and not in the VB6 AI Migrator must be related to issues that have been corrected automatically.
The EWIs present in the VB6 AI Migrator and not in the Upgrade Wizard must be related to old issues that were not marked by the Upgrade Wizard and are identified by the VB6 AI Migrator .
The EWIs present in both upgrades are related to conversions that keep a similar behavior.
Finally, I would like to add that GAPVelocity AI technology has evolved dramatically since the creation of the Upgrade Wizard. We have delivered several VB6 AI Migrator versions, each of which has significantly reduced the costs of the upgrade projects executed by GAPVelocity AI and/or our clients while improving the quality of the generated .NET code.
