Process

A proven path to modernization — one business process at a time

FIG 01SYS.DISCOVER

Illustration of a legacy system mapped for reverse engineering

Reverse Engineering

Pick a business process and point us to the sources. We discover everything at the source — apps, dependencies, data and screens — then auto-generate a full spec: workflow, business rules, data models and roles

.

FIG 02SYS.Integrate

Illustration of legacy and modern systems connected through APIs

Smart Integration

Expose your legacy functions as governed APIs, and simulate every change to validate it before anything moves. Legacy and modern systems keep running side by side — coexistence with zero disruption.

FIG 03SYS.rebuild

Forward Engineering

Rebuild into your target platforms and cloud services. Choose your approach — reimagine, refactor or replatform — your platform, and your LLM. No vendor lock-in.


modernize

Modernize without compromise

01 / DE-RISK

De-risk modernization

The platform uses AI to deeply understand your legacy systems. Built-in safety planning and testing ensure continuous operation while OpenLegacy Hub progressively decouples legacy systems and integrates them into modern architectures.

02 / ACCELERATE

Accelerate time-to-market

Auto-generate standardized, well-documented APIs from legacy systems with AI assistance. Go from complex, hard-to-reach legacy to cloud-native, AI-friendly APIs in days instead of months.

03 / FUTURE-PROOF

Future-proof investments

Stay agile, flexible and future-ready. OpenLegacy Hub is technology-agnostic and fits within any cloud and stack. Stay on-prem, go hybrid, or migrate to the cloud at your own pace.
