The document discusses challenges with modernizing legacy applications, including containing maintenance costs and adapting to changing technology. It notes that VB6 and ASP are becoming outdated and that migrating VB code to newer platforms like C# represents a large market opportunity. A case study is presented of a company that migrated 1.2 million lines of VB6 code to C# using Great Migrations tools, coming in under budget and on schedule while experiencing minimal business disruption during the migration. The methodology used by Great Migrations for migrations is described as tool-assisted, agile, iterative and aimed at balancing risk, cost, and business disruption.

7. BIG PROBLEM: VB/ASP Migration Market Gartner Group Research Rewrite = 60% of original development cost VB6 Conversion Market = $14 Billion Forrester Research “ Migration of VB code is still a large market opportunity -- and the URGENCY is growing” Over 1.2 million U.S. firms still using VB6

8. Case Study: BMS Financial Services BMW Financial Services Large, business-critical VB6 application portfolio 1.2M lines of VB6 400 person-years of accumulated development Strategic policy: avoid unsupported technology Targeting C#.NET with extensive reengineering Saved as much as $8M (70%), finished on schedule, under budget and with no impact on other IT commitments. "We knew that taking our business critical systems through such a huge transformation would be challenging. We needed an approach that not only minimized cost and ensured quality but would insulate our business from disruption. We built new architecture frameworks as a part of the project, and the GreatMigrations translation tools were an essential part of our strategy. These tools, tuned by GreatMigrations to our specifications, have given us the planning flexibility we needed to incorporate the migration into our release process. To this point, we have migrated about 50% of our portfolio, with few of our business users even knowing we were doing it. We are on schedule and on budget to complete the migration by March 2008."
