# Switching your licenses
<a name="switching-licenses"></a>

You can switch your existing operating system (OS) licenses to AWS Marketplace third-party subscriptions without redeploying your Amazon EC2 instances. This reduces downtime and eliminates the need to retest applications.

License switching allows you to convert your Amazon EC2 License Included (LI) operating systems to third-party subscriptions available in AWS Marketplace. For more information about license type conversions, see [License type conversions in AWS License Manager](https://docs.aws.amazon.com/license-manager/latest/userguide/license-conversion.html). After switching, you're billed separately for:
+ Amazon EC2 infrastructure costs (through Amazon Elastic Compute Cloud)
+ OS software costs (through AWS Marketplace)

This feature currently supports Red Hat Enterprise Linux (RHEL) and RHEL for SAP with High Availability and Update Services products.

## Prerequisites

Before switching your licenses, ensure you have:
