Refactor
Improve the existing codebase so teams can release, test, and maintain it more confidently.
Services / Legacy Code Migration
Modernise legacy code without losing operational control
Thrymr helps fintech and financial-services teams migrate, refactor, rebuild, and re-platform legacy systems so they become easier to maintain, integrate, scale, and extend with AI and data capabilities. The team has delivered 20+ end-to-end paper-to-digital migrations.
Positioning
Legacy systems carry the business — and slow it down
They also increase risk, limit integration, and make AI adoption harder. Good migration protects what works while replacing what blocks progress.
For Singapore fintech teams, migration also needs to respect live workflows, business rules, data accuracy, and downstream reporting. The safest path is usually staged, observable, and reversible where possible.
Migration paths
Four ways to move, chosen by risk and constraint
Live systems cannot simply stop while migration happens — the right path depends on how fragile the integrations are and how much of the old architecture can be trusted.
Re-platform
Move the application or workload to a more scalable, reliable, or cloud-ready environment.
Rebuild
Replace parts of the system when old architecture prevents meaningful progress.
Strangle and replace
Move functionality out of the legacy system in controlled slices while the business keeps running.
Outcomes
What success should look like
Fewer release bottlenecks, clearer ownership of business rules, and a roadmap for what to keep, replace, or retire.
Delivery approach
Staged modernisation, not a big-bang rewrite
From system discovery to decommissioning legacy components once the replacement has proven itself.

Assess risk
Map operational risk and migration priorities.
Plan stages
Create a staged modernisation roadmap.
Stabilise
