Legacy software modernization
We move old systems to modern, supported platforms one piece at a time, so the business keeps running while the software underneath it changes.
Good fit if
- Businesses running on software built 10 or more years ago
- Systems only one person still understands
- Applications blocked from the cloud, mobile or integrations by their age
What we do
- System audit
- Code, dependencies, data and the business rules hidden in them, written down before anything changes.
- Incremental rewrite
- An API in front of the old system, then features moved across one at a time until nothing depends on the original.
- Data and database upgrades
- Schema cleanup and migration to a modern SQL or NoSQL database, with both systems kept in sync during the transition.
- New interface
- A modern web or mobile front end on top, so users see improvements early.
How it runs
Inside our standard process: written scope, two-week sprints with demos, and a proper handover.
- 1
System analysis
Architecture, dependencies, risks and a map of what the system really does.
- 2
Modernization plan
Order of migration, target platform, timeline and cost.
- 3
Execute and cut over
Staged migration with testing and rollback at every step, ending in a switch with no downtime.
Tools
VB6, Classic ASP, PHP, .NET Framework, C++, SQL Server, modern .NET, Python, TypeScript, PostgreSQL, AWS, Azure, Google Cloud
Questions
Do we have to stop using the old system during the migration?
No. The old and new systems run side by side, and the switch happens one piece at a time.
Is a full rewrite ever the right call?
Sometimes, for small systems. For anything the business depends on daily, an incremental approach is almost always safer.
Often combined with
- Cloud and DevOps Secure, reproducible infrastructure on AWS, Google Cloud or Azure, with deployments your team can run on a Friday afternoon without worrying.
- Web applications Customer portals, internal tools, dashboards and SaaS products, built to be fast, accessible and easy for the next developer to work on.
- AI consulting We find the places where AI saves real time or money in your business, then build it into the tools your team already uses.
