The old system
is already costing you.
Legacy modernization that keeps the business running while replacing what is holding it back.
Legacy systems do not fail suddenly. They drain you slowly.
The cost of a legacy system is not the day it goes down. It is every sprint slowed by technical debt, every integration that requires a workaround, every new hire who needs months to understand how things work, and every business requirement the system simply cannot support. By the time modernization becomes urgent, the accumulated cost already exceeds what replacement would have cost years earlier.

Modernization without disruption.
Applications, infrastructure, data, and full replacements.
Application Modernization
Monolithic applications refactored into maintainable, deployable architectures. We assess the existing codebase, identify what is worth preserving, and modernize iteratively so the business keeps running throughout. No big-bang rewrites that stop the business for two years.
Cloud Migration and Re-platforming
On-premise systems migrated to cloud infrastructure with the right approach for each workload: lift-and-shift where speed is the priority, re-platforming where the cloud needs to be used properly, and re-architecting where the old design would limit what the cloud can deliver.
Data and Integration Modernization
Legacy data stores, batch processes, and point-to-point integrations replaced with modern data pipelines, APIs, and event-driven architectures. Business data made accessible to the systems and teams that need it, without the fragility of the integrations it replaces.
Legacy System Replacement
End-of-life systems with no viable modernization path replaced with purpose-built alternatives. We scope the replacement correctly, migrate the data, run both systems in parallel through the transition, and manage the cutover so nothing is lost and operations continue without disruption.
No big-bang rewrites.
Phased, low-risk, business-first.
Understand what you have before deciding what to do.
Assessment
We audit the existing system: codebase quality, architecture, data structures, integrations, dependencies, and operational risk. We identify what is worth preserving, what needs to be replaced, and what the business cannot afford to disrupt. The output is a clear picture of the modernization scope and the risks involved in each path forward.
Choose the right approach for each part of the system.
Modernization Strategy
Not every component needs the same treatment. We define the strategy per workload: refactor, re-platform, replace, or retire. Sequencing is determined by business risk, dependency order, and the capacity of the organization to absorb change. A phased roadmap is agreed before any execution begins.
Modernize in increments. Keep the business running.
Phased Execution
We execute the modernization in phases with working deliverables at each stage. Strangler fig patterns, parallel running, and feature-by-feature migration are applied where they reduce risk. The legacy system stays operational until each replacement component is proven in production.
Switch over with a plan, not a prayer.
Cutover and Stabilization
Final cutover is planned, tested, and rehearsed before it happens. Data migration is validated. Rollback procedures are defined. Post-cutover stabilization support is in place before the legacy system is decommissioned. Nothing is switched off until the replacement has proven itself under real load.
Modernization that does not stop the business.
How we reduce risk in every engagement.
No big-bang rewrites.
Full system replacements done in a single cutover are one of the highest-risk moves in enterprise technology. We modernize in phases, keeping the existing system operational until each replacement component is proven in production. The business does not stop while the system changes.
Zero tolerance for data loss.
Every migration we run includes validated data reconciliation before and after cutover. We do not consider a migration complete until row counts, checksums, and business-critical records have been verified against the source. Rollback procedures are defined and tested before they are needed.
Preserve what works. Replace what does not.
Legacy systems often contain years of business logic that is not documented anywhere except in the code. We identify what needs to be carried forward, not just what needs to be replaced. Modernization does not mean starting from scratch — it means keeping the value and removing the constraint.

We had been told it would take eighteen months and cost twice what we had budgeted. Amorisoft delivered in eleven months and came in under budget. More importantly, the business did not stop once during the migration. Not a single outage.
