We received from a German customer these notes, which we gladly (and proudly) publish. As usual, boldface is mine:

On today’s market you have to be able to deliver new application versions at any time. Customers don’t accept statements like: “Sorry, we are in a migration process. We can’t add the feature you need. We can’t even fix a bug within the next year.” VB Migration Partner is the only tool which enables us to enhance the application during the migration process.

It was soon clear to us that the library approach is the way to go. VB6 and VB.NET are too different. It’s not possible for a machine to close this gap. Without VB Migration Partner we would have ended up implementing our own library. The "pragma" concept enables us to run the migration and as a result get .NET code we can compile. With pragmas migration is an ongoing process. We migrate, make changes on the generated code, express these changes in terms of "pragmas" and migrate again. During these migration cycles we are still able to change, enhance and deliver the old VB6 application. VB Migration Partner is a software which gives you the feeling the developers work with it themselves. They know the problems in migration processes and they offer solutions that work.

Conclusion: If you have unlimited time, money and manpower it might be worth having a closer look on the VS built in migration tool. If one of these resources is limited you choose VB Migration Partner.

Some customers ask us whether it is feasible to migrate to .NET without a support library. This customer found the answer by himself: the support library is the only reasonable mean to automatically deliver code that runs correctly. In fact, he says that without VB Migration Partner they would end up building their own library. Fortunately we at Code Architects have spent many man/years to extend and fine-tune our library, thus you can focus on less boring facets of the business.

Equally interesting is that this customer realized that only VB Migration Partner is able to convert VB6 apps that are being modified during the process: this is the methodology we know as “convert-test-fix”. All other conversion tool work on a snapshot of the VB6 codebase, and when the migration seems to be completed you suddenly realize that you still have to re-sync your migrated code with the new features and bug fixes that have been added to the original VB6 code in the meantime.

Not really smart, uh?...but this is how all other VB6 conversion tools work.Wink
