Discuss Your MigrationWhat We Modernise
Legacy Applications
Outdated applications migrated to modern web-based systems. We preserve your business logic while replacing the ageing technology underneath.
Database Migrations
Outdated or outgrown databases replaced with proper web applications and secure, scalable database systems. No more file-sharing issues, corruption risks, or single-user limitations.
Excel-Based Processes
Spreadsheet-based business processes replaced with custom tools offering real-time data, multi-user access, and reporting. No more version conflicts or broken macros.
Desktop-Only Software
Desktop applications converted to cloud-accessible web applications your team can use from anywhere. Work remotely, collaborate in real time, and access your tools from any device.
Outdated Internal Tools
Old internal tools rebuilt with modern, maintainable technology. Stop relying on software that nobody can update and that new team members struggle to learn.
Why This Matters
Legacy systems are a ticking time bomb. They run on unsupported software, they can't be accessed remotely, they depend on one person who "knows how it works," and they're often one hardware failure away from disaster.
Our studio has done this work at a professional level — from migrating legacy ticketing systems to building bespoke intranet platforms and custom business tools. This isn't theoretical; it's hands-on expertise with real-world codebases and complex migrations, delivered with the care and directness of a small specialist team.

Ongoing Support
Maintenance and support available post-launch to keep everything running smoothly.
Frequently Asked Questions
How long does a legacy migration take?
It varies significantly depending on the complexity of the existing system. A straightforward database migration might take 6-8 weeks, while a complex application with extensive business logic could take 3-6 months. We provide a realistic timeline after our initial assessment.
Will we lose any data during migration?
No. Data integrity is our top priority. We perform thorough data mapping and validation, and we run both systems in parallel during the transition period to ensure nothing is lost.
Can you replicate our exact existing workflow?
Yes, and we can usually improve it. We carefully document how your current system works, then build the new system to match — while eliminating inefficiencies and adding capabilities that weren't possible before.
What if our system is undocumented?
That's common with legacy systems. We have extensive experience reverse-engineering undocumented software. We'll work through the system methodically, document the business logic, and verify our understanding with your team before building.
