Delivered a strong proof-of-concept with a module that changed their approach to module-based migration
The client is an industry-leading supplier of automatic test equipment (ATE) and related test software for advanced semiconductor manufacturing companies across the globe. The test software application uses diverse technologies having total around 18 million Lines of Code, and still expanding. The test software is running with 32-bit Excel on 32-bit Windows 7 with hundreds of modules written in different technologies like VBA, VB6, C++, C#, etc.
Client wanted to overcome 32-bit memory limitation and take advantage of 64-bit memory by upgrading from a 32-Bit to a 64-Bit operating environment. Client has their own development environment and team, but they were worried because of the size and time complexity of the project.
The biggest problem was that they were not very confident with their self-designed migration approach and were worried about unexpected results of migration which could probably show up after 1-2 years of development efforts.
Since, 32 bit windows has memory limitation, client wanted to utilize 64bit memory addressing that expands the address space available to meet future memory requirements of the application. Also that will help client in competition and to align to the market trend.
Client wanted us to review their migration approach and provide suggestion for smooth and successful migration, based on our previous experience in migration.
Having expertise in respective technology, we offered the best plan for Upgrading from a 32-Bit to a 64-Bit Operating Environment for each technology and each module of the software application – along with well-defined steps/milestones for the migration.
We used the off-shore and On-site data analysis methodology to completely study their migration approach and major modules of existing software application architecture.
