# Modifying a CEV for RDS Custom for SQL Server
<a name="custom-cev-sqlserver-modifying"></a>

You can modify a CEV using the AWS Management Console or the AWS CLI. You can modify the CEV description or its availability status. Your CEV has one of the following status values:
+ `available` – You can use this CEV to create a new RDS Custom DB instance or upgrade a DB instance. This is the default status for a newly created CEV.
+ `inactive` – You can't create or upgrade an RDS Custom DB instance with this CEV. You can't restore a DB snapshot to create a new RDS Custom DB instance with this CEV.

You can change the CEV status from `available` to `inactive` or from `inactive` to `available`. You might change the status to `INACTIVE` to prevent the accidental use of a CEV or to make a discontinued CEV eligible for use again.

## Console

**To modify 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 modify.

1. For **Actions**, choose **Modify**.

1. Make any of the following changes:
   + For **CEV status settings**, choose a new availability status.
   + For **Version description**, enter a new description.

1. Choose **Modify CEV**.

   If the CEV is in use, the console displays **You can't modify the CEV status**. Fix the problems, then try again.

The **Custom engine versions** page appears.

## AWS CLI
<a name="custom-cev-sqlserver-modifying.cli"></a>

To modify a CEV by using the AWS CLI, run the [modify-custom-db-engine-version](https://docs.aws.amazon.com/cli/latest/reference/rds/modify-custom-db-engine-version.html) command. You can find CEVs to modify by running the [describe-db-engine-versions](https://docs.aws.amazon.com/cli/latest/reference/rds/describe-db-engine-versions.html) command.

The following options are required:
+ `--engine`
+ `--engine-version {{cev}}`, where {{`cev`}} is the name of the custom engine version that you want to modify
+ `--status`` {{status}}`, where {{`status`}} is the availability status that you want to assign to the CEV

The following example changes a CEV named `15.00.4249.2.my_cevtest` from its current status to `inactive`.

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

```
1. aws rds modify-custom-db-engine-version \
2.     --engine custom-sqlserver-ee \ 
3.     --engine-version {{15.00.4249.2.my_cevtest}} \
4.     --status inactive
```
For Windows:  

```
1. aws rds modify-custom-db-engine-version ^
2.     --engine custom-sqlserver-ee ^
3.     --engine-version {{15.00.4249.2.my_cevtest}} ^
4.     --status inactive
```
