# Migrate to Harness CI

Migrate your pipelines to Harness CI and use its build acceleration capabilities.

Use the Harness CI migration utility to move pipelines and access build acceleration capabilities.

### What makes Harness CI unique? <a href="#what-makes-harness-ci-unique" id="what-makes-harness-ci-unique"></a>

Harness CI provides proprietary technologies, like Cache Intelligence and Test Intelligence, which make Harness CI [four times faster](https://harness.io/blog/fastest-ci-tool) than other leading CI tools.

* Harness [Test Intelligence (TI)](/continuous-integration/use-harness-ci/use-harness-ci/run-tests/ti-overview.md) is a proprietary technology that accelerates test cycles by running only the tests necessary to confirm the quality of the code changes that triggered a build. Visualizations show which code changes caused which tests to be selected, and TI can help you identify gaps in your test plan. TI also detects negative trends and provides actionable insights to improve quality. With TI, it's possible to reduce build cycle times by up to 90% without compromising application quality.
* Harness [Cache Intelligence](/continuous-integration/use-harness-ci/use-harness-ci/caching-ci-data/cache-intelligence.md) is a proprietary technology that reduces pipeline execution time by automatically caching well-known directories for languages like Java and Node.js.

Harness CI is part of The [Harness Platform](/harness-platform/new-to-harness-platform/overview.md), which is a self-service CI/CD platform that enables end-to-end software delivery. The Harness Platform includes features, functionality, and additional modules to help you build, test, deploy, and verify software. For example:

* [Secrets management](/harness-platform/use-harness-platform/secrets/secrets-management.md) through the [Harness secrets manager](/harness-platform/use-harness-platform/secrets/secrets-management/harness-secret-manager-overview.md) or an [external secrets manager](/harness-platform/troubleshooting-and-resources/tutorials/add-secrets-manager.md).
* Role-Based Access Control (RBAC) helps you control user and group access to Harness resources according to users' roles. Using RBAC increases security and improves efficiency.
* Harness Policy as Code is a centralized policy management and rules service that leverages the Open Policy Agent (OPA) to meet compliance requirements across software delivery and enforce governance policies.
* The Harness Enterprise Ready Self-Managed Edition is an end-to-end solution for continuous, self-managed delivery. You can install and update Harness Self-Managed Enterprise Edition using online or offline (air-gapped) methods.

### Harness CI Migration Utility

You can use the Harness CI migration utility when migrating pipelines to Harness CI. For details and usage information, see the [Harness migration utility GitHub repository](https://github.com/harness/harness-migrate).
