# Eligible license types for Windows and SQL Server in License Manager
**Important**
Instances that were originally launched from an Amazon provided Amazon Machine Image (AMI) are not eligible for license type conversion to BYOL.
Windows and SQL Server must meet certain requirements in order to be eligible for license type conversion.

## Usage operation values
A license type conversion changes the usage operation value associated with your instance. Usage operation values for each supported operating system are provided in the following table. For more information, see [AMI billing information fields](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/billing-info-fields.html).
| Operating system details | Usage operation |
| --- | --- |
| Windows Server as BYOL | RunInstances:0800 |
| Windows Server as BYOL SQL Server (any edition) as BYOL | RunInstances:0800 |
| Windows Server as license included | RunInstances:0002 |
| Windows Server as license included SQL Server (any edition) as BYOL | RunInstances:0002 |
| Windows Server as license included SQL Server Web as license included | RunInstances:0202 |
| Windows Server as license included SQL Server Standard as license included | RunInstances:0006 |
| Windows Server as license included SQL Server Enterprise as license included | RunInstances:0102 |
## Media compatibility
The following table confirms which media can be used on which instance licensing models.
| Source | Target |
| --- |--- |
| | BYOL | License included |
| --- |--- |--- |
| AWS provided Windows Server image | No | Yes |
| AWS provided SQL Server image | No | Yes |
| Your Windows Server media1 | Yes | Yes |
| Your SQL Server media2 | Yes | Yes |
1 Denotes that the instance was originally launched from your own imported virtual machine (VM). You can import your VM using a service such as [VM Import/Export](https://docs.aws.amazon.com/vm-import/latest/userguide/what-is-vmimport.html) or [AWS Application Migration Service](https://docs.aws.amazon.com/mgn/latest/ug/what-is-application-migration-service.html).
2 Denotes that you have sourced your own SQL Server installation media (.iso, .exe).
## Conversion paths
The following table confirms if the source license model can be converted to another between BYOL and license included. For more information, see [Convert a license type in License Manager](conversion-procedures.md).
**Important**
Windows Server as BYOL with SQL Server as license included is an unsupported configuration.
Conversions that are specified as "Not needed" won't change the usage operation value.
| Source | Target |
| --- |--- |
| | Windows Server as BYOL | Windows Server as license included | Windows Server as BYOL SQL Server as BYOL | Windows Server as license included SQL Server as BYOL | Windows Server as BYOL SQL Server as license included | Windows Server as license included SQL Server as license included |
| --- |--- |--- |--- |--- |--- |--- |
| Windows Server as BYOL (your media) | Not needed | Yes | Not needed | Yes1 | Unsupported | Yes1 |
| Windows Server as license included (your media) | Yes2 | Not needed | Yes1,2 | Not needed3 | Unsupported | Yes1 |
| Windows Server as license included (AWS provided image) | No✗ | Not needed | No✗ | Not needed3 | Unsupported | Yes3 |
| Windows Server as BYOL (your media) SQL Server as BYOL (your media) | Not needed4 | Yes | Not needed | Yes | Unsupported | Yes |
| Windows Server as license included (your media) SQL Server as BYOL (your media) | Yes2 | Not needed4 | Yes2 | Not needed | Unsupported | Yes |
| Windows Server as license included (AWS provided image) SQL Server as BYOL (your media) | No✗ | Not needed4 | No✗ | Not needed | Unsupported | Yes |
| Windows Server as BYOL (your media) SQL Server as license included | Unsupported | Unsupported | Unsupported | Unsupported | Unsupported | Unsupported |
| Windows Server as license included (AWS provided image or your media) SQL Server as license included (AWS provided image) | No✗ | No✗ | No✗ | No✗ | Unsupported | Not needed |
| Windows Server as license included (your media) SQL Server as license included (your media) | Yes2,5,6 | Yes5 | Yes2 | Yes | Unsupported | Not needed |
| Windows Server as license included (AWS provided image) SQL Server as license included (your media) | No✗ | Yes5 | No✗ | Yes | Unsupported | Not needed |
✗ You must deploy a new instance with an alternate configuration, as converting to the target license type(s) is not supported. For more information, see [Media compatibility](#media-compatibility).
For other conversion scenarios, you might need to take the following steps to perform a license conversion:
1 You must first **install** SQL Server before converting to BYOL for SQL Server.
2 You must first modify your Windows configuration to use your own KMS server for license activation. For more information, see [Convert Windows Server from license included to BYOL](conversion-procedures-windows.md#convert-to-byol).
3 You must first **install** SQL Server when you convert from a source without SQL Server to a target with SQL Server (regardless of the SQL Server license type).
4 You must first **uninstall** SQL Server when you convert from a source with SQL Server to a target without SQL Server (regardless of the SQL Server license type).
5 You must first **uninstall** SQL Server before converting to license-included SQL Server.
6 You must first perform the steps for 2 and 5. Once these steps are complete, you must convert the license type to Windows Server as license included, and then convert the license type once more to Windows Server as BYOL.
# Eligible subscription types for Linux in License Manager
License type conversion is available for supported versions of Ubuntu. The supported versions include updates such as Ubuntu 18.04.1 LTS. When you convert a subscription to Ubuntu Pro, security updates are provided for an additional five years. For more information, see [Ubuntu Pro](https://ubuntu.com/pro) in the Canonical documentation.
You can use license type conversion for long-term support (LTS) versions of Ubuntu, RHEL, and RHEL for SAP. You can switch subscriptions between AWS-provided and Red Hat-provided options from AWS Marketplace.
## License type conversion considerations
Some of the considerations that license type conversion is subject to are listed as follows. This is not a comprehensive list and is subject to change.
**RHEL and RHEL for SAP conversion**
+ If you're converting to subscriptions sold by Red Hat as an AMI listing on AWS Marketplace you must first subscribe to the Marketplace AMI listing before initiating the license conversion.
+ For transitions to the Red Hat Subscriptions SaaS listing on AWS Marketplace you need to purchase subscriptions from Red Hat prior to conversion.
+ If you have an annual Red Hat contract from AWS Marketplace you will not receive a refund for unused months when converting to another subscription type.
+ To convert from RHEL for SAP sold by Red Hat in AWS Marketplace to RHEL for SAP sold by AWS in AWS Marketplace send a request to Support. For more information, see [Creating a support case](https://docs.aws.amazon.com/awssupport/latest/user/case-management.html#creating-a-support-case).
**Ubuntu conversion**
+ The instance must be running Ubuntu LTS in order to convert the license type to Ubuntu Pro.
+ You can't use license type conversion for a Ubuntu Pro subscription. To remove a Ubuntu Pro subscription, see [Remove a Ubuntu Pro subscription](conversion-procedures-linux.md#remove-subscription-ubuntu-pro).
+ Ubuntu Pro is not available as a Reserved Instance. For savings with On-Demand Instance pricing, we recommend that you use Ubuntu Pro with Savings Plans. For more information, see [Reserved Instances](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ec2-reserved-instances.html) in the *Amazon EC2 User Guide* and [What are Savings Plans?](https://docs.aws.amazon.com/savingsplans/latest/userguide/what-is-savings-plans.html) in the *Savings Plans User Guide*.
+ To convert from Ubuntu Pro to Ubuntu LTS send a request to Support. For more information, see [Creating a support case](https://docs.aws.amazon.com/awssupport/latest/user/case-management.html#creating-a-support-case).
