Legacy software modernisation
Your old system holds years of business rules. We move them, and your data, onto modern technology without disrupting daily work.
What is legacy modernisation?
Legacy modernisation is the process of updating or replacing outdated software, such as old desktop applications or unsupported frameworks, with modern architectures, while preserving data and business logic and reducing security and maintenance risk.
What our legacy software modernisation covers
Old desktop and PHP systems rebuilt as modern, secure web and mobile software.
System audit
Business rules and data mapped.
Phased migration
Module by module replacement.
Data migration
Validated transfer of historical data.
Modern UI
Web and mobile access.
Security upgrade
Supported, patched technology.
Training
Staff onboarding to the new system.
How we approach legacy software modernisation
Big bang rewrites are risky. We modernise in phases with old and new running side by side.
Data migration is tested repeatedly before cut over.
Every project starts with a short discovery call and ends with software you own: source code, data, cloud accounts and documentation are handed over in your name.
Modules and features
Built for
Technology we use
From first call to launch
The same five stages for every build, with a working demo at the end of each sprint so you see progress, not promises.
Discovery
We map your process, users and data, agree the first release and give you a fixed price for it.
Design
Clickable prototypes of the key screens, reviewed with the people who will use them every day.
Build in sprints
Two week sprints with a demo each time. You can change priorities between sprints.
Test and launch
Functional, security and load testing, data migration, training and a planned go live.
Support and grow
Monitoring, fixes and new features on a monthly plan, or a clean handover to your team.

Learn moreQuestions about legacy software modernisation
Will we lose historical data?
No. Data is migrated and verified before switching.
Can old and new run together?
Yes, during a planned parallel period.
What if nobody understands the old code?
We reverse engineer behaviour from the system and its users.
Do you work only in Kolkata?
Our engineering team is based in New Town, Kolkata, and we work with clients across West Bengal, the rest of India and overseas. Most projects run remotely with weekly demos, and we meet in person when it helps.
