Challenge

This project involves migrating a long-running mainframe core system to a large-scale system within a limited timeframe, while maintaining business operations, and with incomplete specifications.

The architecture was to be changed significantly, data structures were to be normalized, and integration with advanced IT technologies was required.

Customer Voice
Regarding quality, it was absolutely fantastic! We can now connect to the “new IT technologies” we’ve always wanted. Adding features and maintenance will be incredibly easier in the future!

Escaping from a 30-year-old host system was a huge undertaking, but thanks to SoftRoad, we were able to “reborn it beautifully while maintaining high quality.” I’m confident that we’ve created the true “foundation for business innovation”!

Challenge

When migrating third-party (external) plugins and components that were integrated into an older system (VB6) that had been in operation for many years to the .NET environment, there were significant differences in product specifications between the old and new environments.

The schedule was “extremely short” and “absolutely cannot be delayed.” The quality of the migration must also be such that it is easy to modify the functionality after the migration.

Customer Voice
We successfully met the demanding deadline of 5 months and 500,000 lines of code, and achieved extremely high-precision results with zero post-release issues.

This was a great success story that smoothly passed the baton to future system improvements.
