Legacy Modernisation

Signs You've Outgrown Your Current System

• Multiple Excel spreadsheets doing the job of a database
• MS Access crashing, corrupting, or refusing to sync between locations
• Staff working around the system instead of with it
• "Only Dave knows how that spreadsheet works"
• Can't access your data remotely or from mobile
• .NET Framework application stuck on an old Windows version
• New staff take weeks to learn your cobbled-together systems
• You can't get accurate reports without hours of manual collation

If two or more of those sound familiar, your business has outgrown its current tools. The good news: modernisation doesn't have to be painful, expensive, or disruptive.

What Modernisation Looks Like

I don't rip everything out and start again. That's expensive, risky, and disruptive. Instead, I take a phased approach that keeps your business running throughout:

1. Audit — Understand what you have, what works, and what doesn't. Map your data, workflows, and the workarounds your team has built over the years. Often the workarounds reveal the most important requirements.
2. Plan — Design the new system around how you actually work. Not how software thinks you should work. You'll see wireframes and agree the scope before any code is written.
3. Migrate — Move your data carefully. Every record validated. Zero data loss. I've migrated databases with 15+ years of historical data — nothing gets left behind.
4. Build — New application on modern technology. Same familiar workflows, but faster, more reliable, and accessible from anywhere. Regular demos throughout so you can steer direction.
5. Transition — Run old and new in parallel until you're confident. Comprehensive training, user guides, and ongoing support throughout.

Common Migrations

MS Access to Azure SQL + WPF

The most common path. Your Access forms become a proper desktop application with a modern interface. Your Access tables become a cloud database with automatic backups, proper security, and the ability to handle real concurrency. I've done this for companies with 400+ employees.

Typical Access problems I solve: file locking when multiple users edit simultaneously, 2GB database size limits, no proper user permissions, inability to work remotely, and the constant fear of database corruption. The new system eliminates all of these while keeping the workflows your team already knows.

Excel to Proper Database

Spreadsheets are brilliant for ad-hoc analysis. They're terrible as databases. When your business runs on a 200-tab Excel file, it's time for a proper system. Your data moves across, your team gets a proper interface, and you get reliable reporting.

I've seen businesses where a single master spreadsheet was emailed between five people daily, each adding their changes. The version control nightmare alone costs hours every week. A proper database with a purpose-built interface means everyone works on the same live data, with full audit trails and role-based access.

.NET Framework to .NET 8

If you have a working .NET Framework application that needs updating, I can upgrade it to .NET 8 — modern performance, long-term support, and the ability to deploy to current infrastructure. .NET Framework 4.8 is in maintenance mode — no new features, and increasingly difficult to find developers who want to work with it.

Paper-Based Processes to Digital

Some businesses still run on paper forms, whiteboard schedules, and filing cabinets. Digitising these processes doesn't just save time — it creates searchable, reportable data that helps you make better decisions. A job tracking system replaces the whiteboard. A digital form replaces the carbon copy. And suddenly you have visibility into your business that paper could never provide.

What You Get After Modernisation

• Speed — Tasks that took minutes now take seconds. Reports that needed manual collation generate instantly.
• Reliability — No more corruption, crashes, or "the file is locked by another user". Cloud-backed with automatic daily backups.
• Access from anywhere — Work from the office, from home, from site. Your data is always available, always up to date.
• Security — Proper user authentication, role-based permissions, encrypted data storage. Not a shared Access file on a network drive.
• Scalability — Your system grows with your business. Add users, add data, add features — without hitting the ceiling.
• Compliance — Full audit trails, data retention policies, and GDPR-compliant data handling built in from the start.

Typical Timeline and Cost

Every modernisation project is different, but most follow a similar pattern. A straightforward Access-to-cloud migration for a single-department system typically takes 8–12 weeks. Larger enterprise migrations with multiple modules, complex data relationships, and integration requirements may take 3–6 months.
