SY Partners Launches New “Legacy Modernization Support Service”

Tue, 07/15/2025 - 14:37

Legacy system aging and technical debt are significant barriers to DX (Digital Transformation), driving up operating costs and expanding security risks. Especially with mission-critical systems built on older technologies like COBOL or VB6, there are clear and urgent risks, such as difficulties securing engineers and potential maintenance failures.

SY Partners has long delivered system development and migration projects across industries, leveraging local development teams and Japanese-speaking project managers to achieve both cost optimization and quality assurance. Building on this experience, we are now launching our Legacy Modernization Support Service.

1. Service Overview

This service offers end-to-end support—from taking stock of existing systems, selecting the optimal modernisation approach, to design, development, migration, and maintenance. We emphasise deriving and implementing the best solution tailored to each client's system condition, budget, and operational impact.

Key modernisation approaches supported:

Rehost: Lift-and-shift migration to cloud infrastructure without code changes.
Replatform: Minor modifications plus cloud optimisation.
Refactor: Restructuring internal code for improved maintainability.
Rebuild: Full redevelopment to meet new functional requirements.
Replace: Switching to SaaS or packaged solutions for cost optimization.

SY Partners approaches modernization comprehensively—not only from a technical perspective but also with close consideration of business operations, phased migration to reduce disruption, and post-migration adoption support.

2. Main Areas of Support (Vendor/Consulting Delivered)

Our services go beyond simple technology implementation. We provide comprehensive consulting—from assessing existing operations to selecting the best technology, conducting Proof-of-Concept (PoC), building cloud environments, executing migration, and addressing security and governance needs.
