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.
