We have successfully completed over 180 VB migration projects.
At present, we handle over 20 VB migration projects simultaneously each year.
Inevitable VB6 System Update (Migration)
Continuing to use VB6 gives rise to various issues.
Common Problems in Migrating from VB6 to VB.NET
Lack of expertise · Problematic migrations are common
When testing business functions, similar to new developments, it requires significant time, and testing omissions are common.
Lack of experience, incorrect scheme, dependency on people, leaving final verification to customers.
Dedicated tools, appropriate development process and specialized expertise are indispensable for migration.

AppModernizer Testing Features
Comparison test on critical business functions to ensure reliable quality.
We are the only 1 company that tests technical points to ensure high quality, with fewer man-hours and lower cost.
High Quality and Low Cost than Manual/Semi-Automatic Conversion
※¹ This is mainly a fine-tuning of the screen and report UI, and does not affect business logic.
※² “Software Development Analysis Data Collection 2022” relased by the Information-technology Promotion Agency of Japan states the number of defects after release is 0.084 to 0.1 per thousand lines of code (KL).We use this figure as our standard to follow.
※³ Since business logic processing can be converted almost 100% automatically, the number of defects in the business logic portion is extremely low.Minor issues such as display position issues or lack of focus may occur depending on the screen display or operation, but this will not affect the use of the system.
Migration Options
We will propose the best migration plan based on the characteristics of your existing system, your budget, and characteristics of operation management.
