Modernizing Legacy Software — Without Breaking Everything
Is Your Business Running on Outdated Code?
You’re not alone. Many businesses still rely on software built years ago — software that’s critical to operations but painful to maintain, slow to update, and risky to touch.

At Simplico Co., Ltd., we specialize in legacy software modernization — transforming old, fragile systems into clean, testable, and scalable solutions without rewriting everything from scratch.
🧨 The Hidden Costs of Legacy Code
- 🐌 Slow development and bug fixing
- 🔒 Security risks from outdated libraries
- 💸 High maintenance costs
- 🔧 No tests or documentation
- 🧠 Only one developer knows how it works
Sound familiar? These systems aren’t just old — they’re holding your business back.
✅ Our Legacy Re-Engineering Service
We use a structured, risk-aware process to upgrade your software without disrupting your business:
1️⃣ Codebase Audit
We analyze your software with tools like FindBugs, PMD, SonarQube, and Jenkins to identify weak points, risks, and areas of improvement.
2️⃣ Safe Refactoring & Testing
We introduce automated tests, isolate business-critical logic, and refactor incrementally to improve code health and flexibility.
3️⃣ Infrastructure Modernization
Using Vagrant, Ansible, and modern CI/CD pipelines, we automate development and deployment environments — no more “it works on my machine.”
4️⃣ Scalable Architecture
If needed, we redesign modules or break monoliths into manageable services — always based on your business goals, not hype.
