App Modernization
Refactor outdated applications into scalable, high-performing systems.
Overview
Why teams choose Kryon for App Modernization
From .NET monoliths to legacy Java estates, we modernize applications with the strangler-fig pattern — one capability at a time, with zero big-bang risk.
What We Do
Core capabilities
Strangler-Fig Migration
Replace pieces incrementally while the legacy keeps running.
Containerization
Dockerize, then orchestrate with Kubernetes or serverless.
API-First Refactor
Wrap legacy with clean APIs to unlock new front-ends.
Data Untangling
Split shared databases into bounded-context stores.
Security Uplift
Patch the gaps that legacy systems quietly accumulated.
Performance Tuning
Find the 10× wins hiding in profiling data.

Two decades of shipping software across heavily regulated, data-rich and operationally complex industries.
FAQs
Frequently asked questions
Will the legacy keep running during migration?
Yes — strangler-fig means traffic flips per slice, not per system.
How do you handle data security and IP protection?
Every engagement starts with an NDA. We follow ISO 27001 controls — locked-down workstations, VPN-only access, encrypted backups, and least-privilege repository access. All IP, source code and design files transfer to you on delivery.
What does pricing look like?
We offer fixed-price for well-defined scope, time-and-materials for evolving work, and dedicated-team retainers for long-term partnerships. Most clients start with a fixed-price discovery and convert to a retainer after the first release.
Do you offer a trial or paid pilot?
Yes — for new partnerships we run a 2-week paid pilot with a clear deliverable. If you're not satisfied, we part ways with no further commitment.
How do you communicate during the project?
Daily async updates, twice-weekly standups, weekly demos, and a dedicated Slack channel. You'll always know what's shipping next, what's blocked, and where the team needs your input.
