# Step 2: Launch the transfer workflow
<a name="step-2-launch-the-transfer-workflow"></a>

**Important**  
Avoid starting multiple transfers simultaneously. Multiple transfers can exceed Amazon Glacier quotas and induce throttling.  
When you transfer multiple vaults, initiate transfers sequentially by starting a new transfer only after the previous one completes.

1.  Sign in to the [Systems Manager console](https://console.aws.amazon.com/systems-manager). 

1.  Under **Shared Resources**, select **Documents**. 

1.  On the **Documents** page, select **Owned by me**, and choose the document called `Launch-Data-Retrieval-for-Glacier-S3-${{<NAME_OF_STACK>}}`. 

1.  Choose **Execute Automation**.

 If you want to download the vault inventory file as part of this migration, follow these steps. 

1.  Sign in to the [Systems Manager console](https://console.aws.amazon.com/systems-manager). 

1.  Under **Shared Resources**, select **Documents**. 

1.  On the **Documents** page, select **Owned by me**, and choose the document called `Launch-Data-Retrieval-for-Glacier-S3-${{<NAME_OF_STACK>}}`. 

1.  Choose **Execute Automation**. 

1.  Enter the following under **Input Parameters** on the **Execute Automation Runbook** page. 
**Note**  
To enable the data transfer to a bucket in a different region from the S3 Glacier vault, you must manually adjust the automation document's content by setting the InputPayload parameter ` allow_cross_region_data_transfer` to true. By default, the Guidance restricts cross-region transfers to avoid potential costs.

1. Choose **Execute**.

1. It takes approximately less than 1 minute to execute the document and launch the transfer. To confirm that the transfer process started successfully, refer to the ***runScript ***step status under the ***Executed Steps*** section.
**Note**  
To monitor the progress of the transfer after launching the workflow, please refer to the Guidance’s [Cloudwatch dashboard](use-the-guidance.md#access-the-cloudwatch-dashboard). Please note that it might take 5-12 hours before the dashboard ***Workflow Run ID*** dropdown menu entries get updated with the new entry after launching the transfer.

 If you want to provide the vault inventory file, follow these steps. 

1.  Sign in to the [CloudFormation console](https://console.aws.amazon.com/cloudformation). 

   1.  On the **Stacks** page, select this Guidance's installation stack. 

   1.  Choose the **Output** tab and find the inventory bucket name. 

1.  Sign in to the [Amazon S3 console](https://console.aws.amazon.com/s3) and choose the inventory bucket from step 1b. 

   1.  Choose **Create folder**. Enter the `workflow_run` value from the **WorkflowRun** parameter input. For more information about creating and using folders, see [Organizing objects in the Amazon S3 console by using folders](https://docs.aws.amazon.com/AmazonS3/latest/userguide/using-folders.html) in the *Amazon Simple Storage Service User Guide*. 

   1.  Create a subfolder called `original_inventory` in this new folder. 

   1.  Copy the vault inventory file into this folder. For more information, see [Downloading a Vault Inventory in Amazon Glacier](https://docs.aws.amazon.com/amazonglacier/latest/dev/vault-inventory.html) in the *Amazon Glacier Developer Guide*. 

   1.  Rename the vault inventory file to `inventory.csv`.
