Legacy Modernisation

Modernise legacy applications and replace risky spreadsheet processes

We help organisations move ageing applications, unsupported codebases and business-critical spreadsheets toward maintainable, secure and integration-ready platforms.

Where this service helps

Business problems this engagement is designed to solve

  • A business-critical system runs on ageing or unsupported technology.
  • Only one person understands a spreadsheet or legacy application.
  • Security and access control are difficult to manage.
  • The current platform cannot integrate with modern services.
What we can deliver

A practical scope built around the operating requirement

The final scope is shaped around your systems, users, data, risk profile and business outcome rather than a fixed feature package.

Legacy application assessment

Phased .NET modernisation

Database migration and cleanup

Excel-to-web-application migration

Integration enablement

Cloud migration and support

Delivery approach

Modernise in phases instead of creating unnecessary replacement risk

A staged approach lets the organisation preserve working business rules and data while replacing the highest-risk components first.

Document current business rules
Identify unsupported dependencies
Separate data migration from feature redesign
Release in controlled phases
Technology fit

Platforms and integration patterns we work with

.NET / ASP.NET Core SQL Server Azure REST APIs Legacy .NET Excel migration
Frequently asked questions

Questions organisations ask before starting

Can you turn an Excel process into a web application?

Yes. The first step is to identify the real business rules, data model, users and approvals currently hidden inside the workbook, then move them into a governed application.

Do we have to replace the whole legacy application at once?

No. Many modernisation programmes are safer when functionality, integrations and user groups are migrated in phases.
