OL-Hub Planner: Modernizing with Confidence

OpenLegacy Hub Planner is a core component of OpenLegacy's phased and agile modernization strategy, which is designed to help enterprises transform their mission-critical legacy systems with minimal risk and disruption. This evidence-based framework balances innovation with operational continuity, ensuring you can deliver new digital capabilities immediately while progressively moving workloads to the cloud.

Enterprises that successfully modernize their legacy systems can realize dramatic gains, including up to 353% ROI and 45% lower IT operating costs. OpenLegacy's approach is built to de-risk coexistence, which is essential as you face competitive pressures and demands for faster release cycles, AI-readiness, and cost rationalization.

Key Benefits of OpenLegacy's Approach

Reduce Modernization Risk through pre-migration dependency mapping and automated service generation. The Hub Planner is used to visualize inter-program calls, database touchpoints, and batch schedules as the first step in the implementation roadmap.
Adopt a Step-by-Step Strategy that delivers measurable value early without the cost or disruption of a "big-bang" cut-over. This strategy adapts to any modernization methodology, whether you choose to refactor, re-platform, rewrite, or retain applications.
Future-Proof Your Investments by exposing core business logic and data as cloud-ready APIs that fuel analytics and AI initiatives.
Decouple Safely at multiple layers (internal, external, data-layer, and logic-layer) using a library of proven decoupling patterns to enable legacy and cloud workloads to run side-by-side. The guiding principle is to decouple only as much as necessary for the next modernization step, avoiding unnecessary rewrites.

How OpenLegacy Responds to Modernization Challenges

The OpenLegacy Hub addresses traditional modernization blockers by removing complexity, skills gaps, slow integration cycles, and downtime risk.

Challenge	How OpenLegacy Responds
System Complexity & Hidden Dependencies	Hub Planner automatically maps program calls, database interactions, and batch dependencies. Generated façade APIs encapsulate complexity while automated contract tests provide guardrails.
Skills Shortage & Tribal Knowledge	Low-code wizards, AI-assisted code templates, and a rich connector catalog reduce reliance on scarce mainframe specialists.
Manual Integration Effort	Automated API generation and pre-configured connectors compress interface delivery to days or weeks, bypassing traditional middleware.
Zero-Downtime Mandate	The Phased Co-Existence Framework keeps legacy and cloud workloads running side-by-side with rolling, validated releases.

The OpenLegacy Hub automates every stage of modernization, from dependency analysis to API generation and deployment, offering a continuous, structured path to transformation.
