What we do

Right application. Right platform. Right pace.

Kyndryl helps enterprises continuously modernize mainframe applications using production insight, agentic AI and expert guidance. We assess business value, dependencies, risk, cost and technical readiness to determine the right path for each application, whether that means modernizing on the mainframe, integrating with new platforms or moving off entirely. Human-led governance and coexistence strategies help protect business continuity while transformation progresses.

How Kyndryl help

Our mainframe modernization capabilities

Modernize on the mainframe

Improve applications, data access, developer experience, performance, resilience and cost while retaining the right workloads on IBM Z or IBM i.

Integrate with cloud, data and AI

Expose trusted mainframe applications, data and transactions through APIs, events and modern integration patterns without compromising core resilience.

Move off selectively

Replatform, refactor, replace or retire applications where business value, risk, economics and readiness justify a different platform.

Accelerate every path with agentic modernization

Use agentic workflows to accelerate discovery, dependency analysis, business-rule extraction, dispositioning, design, code transformation, testing and assurance - with expert validation and governance throughout.

Why work with us?

Strategy - dark version

We run what we transform, and we transform what we run

Running mission-critical estates gives Kyndryl valuable production context, including business rules, dependencies, data flows, batch behavior, cost, controls and operational risk. That leads to more informed modernization decisions. We then operate the transformed environment, use AI-enabled operations to improve the run state and apply new production insight to guide what changes next.

Agentic accelerated. Expert governed.

Reusable agentic workflows accelerate discovery, analysis, decision support, documentation, engineering, testing and assurance while Kyndryl experts validate decisions, artifacts and progression to production. Human oversight, governance and policy controls help maintain trust, resilience and accountability.
