Thoughts and findings about the software migration world... plus the inevitable random rants and cogitations eventually.

  • Successfully handling a complex, highly-sensitive migration project – The Banamex/Citigroup case study

    A while ago, I blogged on the benefits of migrating from VB to .NET, based on an analysis that one of our customers did before engaging in the upgrade process. They had about 124 applications, for a total of more than 5 million lines of VB6 and ASP code that needed to be migrated to C# and ASP.NET to comply with corporate policies, while they expected more than US$40M of accumulated benefits in 5 years as a result of this investment.

     

    Well, the migration was completed some time ago, and they’ve been including several other applications during the process, and we’ve just released the case study for the original engagement. The customer is Banamex, a leading Mexican bank, part of Citigroup, and the project implied an unparalleled methodology for collaboration between customer and provider teams, taking into account that Citigroup’s information security policies required to establish an appropriate mechanism for protection of sensitive data. Not to mention extremely tight deadlines!

     

    The business logic and functionality had to remain intact, and dependencies with non-authorized providers, like proprietary runtimes, were just out of the question, and using ArtinSoft’s Visual Basic Upgrade Companion allowed reaching 100% functional equivalence on time and on budget.

  • How an ISV saved more than 3 years and $300,000 migrating from VB6 to VB.NET

    We’ve just released a new case study that shows how one of our customers saved lots of time and money by using our Visual Basic Upgrade Companion tool to migrate its flagship application from VB to .NET. Based in South Africa, MDA Property Systems provides software solutions to the real state sector. Its MDA Property Manager application is a comprehensive package for rent collection, lease management, facilities management, integrated property accounting and asset management, employed by more than 1800 users across 250 companies. With more than 600,000 lines of VB6 code it encapsulated decades of business knowledge, so MDA licensed our tool to perform the conversion to VB.NET with minimal risk and using their own internal resources, after discarding a manual rewrite and the Upgrade Wizard

     

    Also, it was very important for MDA to use the newest technology instead of just being able to run Visual Basic 6 style code inside the .NET Environment, and using ArtinSoft’s Visual Basic Upgrade Companion guaranteed that they will be getting native .NET code, without any ties to third-party runtimes. RDO was transformed to ADO.NET, third party controls were converted to native .Net controls, Component One’s True DB grid was upgraded to the latest version of that component, and coding standards that were common place when developing in Visual Basic 6.0 were also migrated to equivalents in VB.NET. It allowed MDA to save on valuable resources: total savings for this project were more than 3 years of development time and US$300,000, and they are now ready to start taking advantage of compelling new features that will extend the technological life of its product.
