# Deleting a CEV for RDS Custom for SQL Server
Deleting a CEV for RDS Custom for SQL Server

You can delete a CEV using the AWS Management Console or the AWS CLI. Typically, this task takes a few minutes.

Before deleting a CEV, make sure it isn't being used by any of the following:
+ An RDS Custom DB instance
+ A snapshot of an RDS Custom DB instance
+ An automated backup of your RDS Custom DB instance

## Console


**To delete a CEV**

1. Sign in to the AWS Management Console and open the Amazon RDS console at [https://console.aws.amazon.com/rds/](https://console.aws.amazon.com/rds/).

1. In the navigation pane, choose **Custom engine versions**.

1. Choose a CEV whose description or status you want to delete.

1. For **Actions**, choose **Delete**.

   The **Delete *cev\$1name*?** dialog box appears.

1. Enter **delete me**, and then choose **Delete**.

   In the **Custom engine versions** page, the banner shows that your CEV is being deleted.

## AWS CLI


To delete a CEV by using the AWS CLI, run the [delete-custom-db-engine-version](https://docs.aws.amazon.com/cli/latest/reference/rds/delete-custom-db-engine-version.html) command.

The following options are required:
+ `--engine custom-sqlserver-ee`
+ `--engine-version cev`, where *cev* is the name of the custom engine version to be deleted

The following example deletes a CEV named `15.00.4249.2.my_cevtest`.

**Example**  
For Linux, macOS, or Unix:  

```
1. aws rds delete-custom-db-engine-version \
2.     --engine custom-sqlserver-ee \
3.     --engine-version 15.00.4249.2.my_cevtest
```
For Windows:  

```
1. aws rds delete-custom-db-engine-version ^
2.     --engine custom-sqlserver-ee ^
3.     --engine-version 15.00.4249.2.my_cevtest
```
