Product Modernisation
Modernise What You Have Without Losing What Works
Your legacy application still works — but it is expensive to maintain, difficult to recruit for, and impossible to extend. FI Digital modernises legacy systems with modern architecture, without losing the business logic your team depends on. No rip-and-replace. No big-bang rewrites. Structured, phased modernisation that keeps your business running throughout.
Trusted by Australian enterprise clients.
The Modernisation Dilemma
Every organisation with a legacy application faces three paths. Two of them are traps.
Path 1 — Full Replacement
Big-bang rewrite that takes two years, costs three times the estimate, and still does not do everything the original did.
Path 2 — Do Nothing
Recruiting developers for dying frameworks. Maintenance costs that grow each year. Competitors building features your system cannot support.
Path 3 — FI Digital Approach
Structured, phased modernisation that preserves what works, replaces what does not, and keeps your business running throughout.
Our Modernisation Approaches
Five distinct approaches — one chosen based on your system's condition, risk profile, and business requirements.
How We Audit Before We Modernise
We do not begin modernisation without understanding what we are modernising. Our audit covers six dimensions and produces a Modernisation Architecture Document.
Recommended approach, phasing plan, risk profile, and investment estimate — before you commit to anything.
Size, complexity, test coverage, dependency mapping, framework versions, and security vulnerability scan.
Capturing undocumented workflows and validation rules that live only in people's heads — before anyone leaves.
Schema analysis, data quality assessment, and identification of data that can be cleaned during migration.
Every external system the application connects to — APIs, file shares, scheduled jobs, and database links.
Current response times, concurrency limits, database query performance, and known failure modes under load.
Authentication, authorisation, session management, input validation, known CVEs, and data exposure risks.
