# DeleteSchemaVersions
<a name="API_DeleteSchemaVersions"></a>

Remove versions from the specified schema. A version number or range may be supplied. If the compatibility mode forbids deleting of a version that is necessary, such as BACKWARDS\$1FULL, an error is returned. Calling the `GetSchemaVersions` API after this call will list the status of the deleted versions.

When the range of version numbers contain check pointed version, the API will return a 409 conflict and will not proceed with the deletion. You have to remove the checkpoint first using the `DeleteSchemaCheckpoint` API before using this API.

You cannot use the `DeleteSchemaVersions` API to delete the first schema version in the schema set. The first schema version can only be deleted by the `DeleteSchema` API. This operation will also delete the attached `SchemaVersionMetadata` under the schema versions. Hard deletes will be enforced on the database.

If the compatibility mode forbids deleting of a version that is necessary, such as BACKWARDS\$1FULL, an error is returned.
