Three Core Principles

Legacy migration is key to staying competitive, secure, and innovative—but too often these projects derail under complexity and risk. Our approach makes migration safe, fast, and disruption-free.

Live Systems Define Requirements
We understand systems by creating comprehensive digital twins that capture actual data flows and runtime patterns. This approach respects your privacy while creating a complete understanding of how your code really works.
Mirror Operations in Modern Frameworks
Using runtime data flows, we generate high-quality, maintainable code in cloud-native languages that functions identically to your original system.
Deploy Progressive Updates
We modernize component by component, with each increment proven through digital twin validation before moving to the next. This profoundly limits risk at any given time.

Why Traditional Migration Fails

Common approaches today have serious drawbacks that our behavioral replication approach solves.

Migrating "As-Is" Postpones the Problem
Moving legacy code to the cloud "as-is" means the code is still old, constraints still exist, and the skill set keeping it going is still fading as people leave the workforce.
Converting Code Creates New Problems
Automated tooling rewrites code that few understand into machine-generated code that now nearly no one does, creating further constraints and delays.
Big-Bang Overhauls Impose Serious Risks
Reimagining entire systems involves interfering with multiple dimensions simultaneously, without knowing if everything works until the very end—causing massive delays and costs.

Frequently Asked Questions

Everything you need to know about our behavioral replication approach.

Wait, so you want to replicate an old system before I can do anything new?
Software evolution follows a simple principle: stabilize before you innovate. We believe the fastest and safest path forward is by rebuilding what's already working effectively. Since we deliver incrementally, you can start innovating on each slice as soon as it's modernized.
How does Bevel's approach differ from traditional migration?
We focus on system behavior rather than legacy code. This creates a "test harness" that guides the rewrite, ensuring exact behavioral replication in modern languages. We work iteratively rather than tackling entire systems at once, reducing risk through frequent releases.
What programming languages does Bevel support?
The beauty of our approach is that we capture data flows across component interfaces and treat components as black boxes. Because we reproduce behavior based on data flows, language choice (either source or target) doesn't matter—we can work with any language.
How does Bevel use AI to generate code?
We capture data inputs and outputs to generate high-quality, idiomatic modern code that's built and verified rapidly against actual runtime data through our digital twin approach. This eliminates the long and uncertain period of "testing and integration" that often results in project failures.
Who would be the best candidates for Bevel's approach?
Companies looking to the cloud for competitive edge are ideal. Our iterative approach means critical workflows can begin modernizing in weeks, not years, without going offline. Organizations can capture market opportunities quickly and accelerate or decelerate as timing and market cycles allow.
Can you help eliminate technical debt?
Yes. We rewrite entire applications into cloud-native, idiomatic, easily maintainable code that exactly replicates existing behavior. This gives you a "fresh start" without disrupting business flow and resets the technical debt meter—slice by slice, avoiding any disruption.
