Supporting up to 80% reduction in man-hours. Launch of VB6 migration solution 'CodeShift VB'

NEWWAVE SOLUTIONS JAPAN Co., Ltd. (Location: Bunkyo-ku, Tokyo) will start accepting consultations for 'CodeShift VB', a migration support solution from VB6 to VB.NET, from June 2026.

Protect your VB6 assets while migrating to VB.NET.

'CodeShift VB' is a migration support solution that combines AI-powered automatic compilation error analysis with engineer-led quality verification. Based on a track record of migrating over 200,000 lines of code, reducing refactoring man-hours by 80%, and stabilizing approximately 90% of compilation errors, it supports safe and reliable migration.

Amid the warnings of the '2025 Digital Cliff', this is a solution for companies with aging and black-boxed VB6 systems.

Background: Challenges of Legacy Systems

In many Japanese companies, legacy systems, particularly those based on Visual Basic 6.0 (VB6), still support critical business operations. However, structural issues such as aging, increasing complexity, and black-boxing are becoming more severe, posing a major barrier to DX promotion.

The '2025 Digital Cliff' warned about in the Ministry of Economy, Trade and Industry's 'DX Report' points out that if responses to these system issues are delayed, it could lead to an annual economic loss of up to 12 trillion yen.

The core issues can be summarized into three main points.

First, the black-boxing of business logic. Business logic accumulated over years of operation remains in the source code, and it is often not adequately organized in design or specification documents.

Second, increasing maintenance and modification costs. As it becomes more difficult to secure engineers proficient in VB6, man-hours and costs tend to increase with every failure response or functional modification.

Third, limitations in adapting to modern environments. It becomes difficult to respond to cloud integration, API connections, and AI utilization, potentially affecting the introduction of new technologies and the creation of business opportunities.

These issues are recognized not merely as IT infrastructure problems but as management challenges directly linked to a company's competitiveness and growth strategy.

'CodeShift VB': Reliable Migration from VB6 to VB.NET.

'CodeShift VB' is a VB6 to VB.NET migration support solution independently developed by NEWWAVE SOLUTIONS. It supports the entire migration process end-to-end, from code conversion to compilation error analysis and correction, engineer verification, and change history management.

Based on a track record of migrating over 200,000 lines of code, it achieves safe and reliable modernization while preserving existing business logic.

Key Features of CodeShift VB

① Structured Code Conversion
Analyzes VB6 code and supports structured conversion to the VB.NET environment while inheriting business logic.

② AI-Assisted Compilation Stabilization
AI automatically analyzes compilation errors and suggests corrections. By applying these after engineer review and approval, refactoring man-hours are reduced by up to 80%.

③ Engineer-Led Quality Verification
All conversion results are reviewed and verified by engineers. This achieves production-quality migration while minimizing the impact on business logic.

④ Change History Visualization and Governance
Centralizes management of conversion details, correction history, and verification status, ensuring traceability for project management, internal reporting, and quality audits.

Expected Benefits of Introduction

① Optimization of Maintenance Costs
By organizing and visualizing the system structure through migration to VB.NET, man-hours for failure response and feature additions are reduced, achieving long-term operational cost optimization.

② Elimination of Personalization Risk
By visualizing business logic and change history, dependence on specific individuals is eliminated. This facilitates smooth internal confirmation and handovers, supporting the establishment of a stable maintenance structure.

③ Enhanced Capacity for DX Promotion and Business Expansion
By establishing a foundation for integration with modern environments, subsequent steps such as API integration, data utilization, and AI implementation are accelerated. This supports a structure that allows for quick steps into new service development and business improvement.
