While it is uncommon for a scenario to arise where the license must be removed from Veeam ONE, it can be done. Removing the license from Veeam ONE will revert it to the Community Edition feature set. The Veeam ONE license can only* be removed using REST API.

^{*If the Veeam ONE server is managed from a Veeam Service Provider Console, the license can be removed remotely.}

The steps below will demonstrate how to remove the license using the built-in Swagger UI.

1. On the Veeam ONE server, open a web browser and go to https://localhost:1239/swagger/index.html
2. Authorize by following Step 1 and Step 2 on this page: Veeam ONE REST API Reference - Getting Authorization Tokens
   ^{Note: Read step 2 of the Getting Authorization Token guide very carefully.}
3. Once Authorized, expand the Licensing section and expand the entry named: POST ​/api​/v2.2​/license​/remove Delete License
4. Click the "Try it out" button.

6. Then, click the "Execute" button.

After clicking Execute, the page will update to display a "Server response."

If it returns Code 200, the license was removed successfully.
