Home / Services / Legacy Software Modernisation
Notion Tech rebuilds ageing business systems, such as Access databases, giant spreadsheets, old desktop programs and unsupported PHP sites, on modern, secure technology. We move your data across, keep the business running during the change and train your team on the new system.
// before: orders.mdb, macros, one PC in the office
await migrate({ from: "access", to: "postgres" })
await verify(rows) // every record checked
// after: web app, phones, backups, audit log
Keep what works. Replace what holds you back.
Multi-user web apps that replace fragile databases and shared spreadsheets.
Programs tied to one office PC rebuilt to work securely from any browser or phone.
Unsupported code replaced with maintainable, tested software.
Years of records cleaned, moved and checked, with nothing left behind.
Connect the new system to Xero, Stripe, payroll and your other tools.
Logins, roles, encryption, audit logs and automatic backups from day one.
Legacy systems rarely fail all at once. They get slower, only one person understands them, they cannot be used from home or a phone, and every change feels risky. Often the software they depend on is no longer supported, which is a security problem as well as a practical one.
If your team keeps a second spreadsheet "because the system can’t do that", or you are worried about what happens when a key person leaves, it is time to plan a replacement.
We start by documenting what the old system really does, including the unwritten rules staff carry in their heads. Then we rebuild in stages, running old and new side by side where needed, and migrate data with checks at every step.
Staff are trained before go-live, and the old system stays available read-only until everyone is confident. The result is a modern system your business can keep improving, instead of one it is afraid to touch.

Still have a question? Talk to us.
Yes. We rebuild them as secure web apps that many people can use at once, from the office, home or a phone, and we migrate your existing data.
No. Data migration is planned, rehearsed and checked. We reconcile record counts and totals between the old and new systems before go-live.
No. We build in stages and can run both systems side by side, so the business keeps operating.
That is common. We read the code and data, talk to the people who use it and document it before rebuilding.
A small system can take 6 to 10 weeks. Larger systems are staged over several months, with the highest-risk parts first.
