Legacy Migration

Safe, fast, high-quality migration — powered by AI.

Migrating legacy assets by hand carries enormous effort and the risk of human error. Using AI-assisted asset analysis and customized conversion tooling, we cut effort, reduce mistakes, and assure quality at the same time.

Value

What Migration Delivers

Less effort, shorter timelines

Asset analysis and automated conversion compress the manual work that migration used to require.

Fewer mistakes

Automating repetitive work reduces the risk of rework and incidents caused by human error.

Higher productivity and quality

We do not stop at conversion: functional verification and performance evaluation secure quality after migration.

Strengths

Our Strengths

1

Asset analysis

We analyze existing code, databases, screens, and batch jobs, and help you decide whether to move each asset as-is or rewrite it.

2

Conversion tool customization

For complex assets that generic tools cannot fully handle, we design conversion rules tailored to your environment.

3

Lower effort, fewer mistakes

Raising the automation rate cuts repetitive work and human error, and makes effort visible.

4

Production-grade quality

We do not stop at conversion: we carry out functional verification and performance evaluation to confirm the result can stand up in production.

Scope

Scope and Coverage

We take on the whole sequence — analysis, conversion, migration, and verification — as one engagement. Databases, applications, cloud, and on-premises are all in scope.

Mainframe Systems

We move long-running mainframe assets onto modern open platforms.

  • COBOL → Java
  • COBOL → MF COBOL

Client / Open Systems

We rebuild on obsolete languages and screen UIs into maintainable environments.

  • VB6.0 → VB.NET
  • Flex → HTML5

Java Framework Upgrades

We migrate off end-of-support foundations onto current standard configurations, step by step.

  • Seasar / Struts / Spring → Spring Boot
  • TerasolunaX → Terasoluna5

Platform Updates

We resolve breakage caused by end-of-life operating systems and browsers by updating the environment itself.

  • Windows / Windows Server / IE → Edge

Database Updates

We guide you through version upgrades and cross-DBMS migrations, starting from the design phase.

  • Oracle / SQL Server etc. → Latest version
  • Oracle / SQL Server → PostgreSQL

Front-end Modernization

We re-implement screens that depend on discontinued plugins using modern web technology.

  • Adobe Flash Player → HTML5
  • Flex / Silverlight → Angular

Process

How the Migration Runs

1

Asset analysis

We analyze the structure, volume, and dependencies of the target system.

2

Migration strategy

We decide what to move and what to rewrite, and fix the scope and approach.

3

Tool design & customization

We design conversion rules matched to your assets.

4

Conversion & implementation

We run the conversion and refine by hand where needed.

5

Verification

We confirm quality through functional verification and performance evaluation.

6

Post-migration support

We support adoption and maintenance after go-live.
