**To update a workflow version**

1. Open the [HealthOmics console](https://console.aws.amazon.com/omics/).

1.  If required, open the left navigation pane (≡). Choose **Private workflows**.

1. On the **Private workflows** page, choose the workflow.

1. On the **Workflow** page, choose the workflow version to update and choose **Edit selected** from the **Actions** list. 
   + If you choose the default version, the console opens the **Edit workflow** page. For more information, see [Update a private workflow](update-private-workflow.md).
   + If you choose a user-defined version, the console opens the **Edit version** page. 

1. On the **Edit version** page, provide the following information
   + **Version description** (optional) - A description of this version.

1. In the **Default run storage configuration** panel, provide the following default values for runs that use this workflow version. You can override the default values when you start a run:
   + For **Run storage type**, select **Static** or **Dynamic**.
   + For static run storage, select the default amount of **Run storage capacity** for runs that use this workflow version. The default value for this parameter is 1200 GiB.

1. Choose **Save changes**.

The console returns to the workflow detail page and displays a page banner with the updated workflow version.

## Update a workflow version using the CLI
<a name="workflow-versions-api-update"></a>

You can update parameters for a workflow version using the following CLI command. The combination of workflow ID and version name uniquely identifies the version. 

```
aws omics update-workflow-version
--workflow-id 1234567
--version-name "my_version"
--storage-type 'STATIC' 
--storage-capacity 2400
--description "version description"
```

You receive no response to the `update-workflow-version` request. 

## Update a workflow version using an SDK
<a name="workflow-versions-sdk-update"></a>

You can update a workflow version using one of the SDKs. The following python SDK example shows how to update the storage type and description for a workflow version.

```
import boto3

omics = boto3.client('omics')

response = omics.update_workflow_version(
   workflowID=1234567,
   versionName='3.0.0',
   storageType='DYNAMIC',
   description='new version description'
)
```
