Legacy Application Migration for Wang BASIC & Niakwa NPL

What is legacy application migration?

Legacy application migration is moving a business application off an aging platform onto a modern one without losing the logic and data it holds. For many New England companies, that application was written decades ago in Wang BASIC and later kept running on PCs and servers through Niakwa’s NPL runtime.

When Wang Laboratories declined in the 1990s, Niakwa’s NPL and NPL-RTE let businesses keep running Wang applications on DOS, Windows, UNIX and later Linux without rewriting them. Organizations in government, manufacturing and insurance, among others, still run them today.

Can Wang BASIC and NPL applications move to Windows, Linux or the cloud?

Yes, Wang BASIC and NPL applications can be migrated to Windows, Linux or cloud environments. The right target depends on who uses the application, where your other systems run, and how much of the original code you want to keep.

We understand both the historical structure of Niakwa systems and today’s business technology standards, so we can plan a move that doesn’t disrupt operations.

What happens to our data during migration?

Your data is converted from legacy file formats into SQL databases and validated so nothing is lost or changed in the move. Years of records locked in proprietary files become queryable with standard tools.

• Conversion from Wang and Niakwa data files to SQL databases
• Validation between the old and new data
• Regular backups and disaster recovery planning around the transition

Do we have to rewrite the whole application?

No, migration does not have to mean a full rewrite: we keep what works and modernize what doesn’t. Depending on the application, that can mean several paths.

• Refactoring existing code to extend functionality or enable web-based access
• Re-platforming line-of-business applications into modern frameworks such as Blazor
• Adding modern APIs and interfaces around a proven core

Can a migrated application connect to our ERP, CRM or analytics tools?

Yes, integration with modern ERP, CRM and analytics platforms is a core part of migration. Once data lives in SQL, it can feed reporting, dashboards and other business systems instead of sitting in isolation. We also build interfaces between Niakwa data and third-party software, and automate workflows and reporting. Learn more about our systems integration work.
