# Migrating to Amazon FSx for Lustre using AWS DataSync
<a name="migrating-fsx-lustre"></a>

You can use AWS DataSync to transfer data between FSx for Lustre file systems. DataSync is a data transfer service that simplifies, automates, and accelerates moving and replicating data between self-managed storage systems and AWS storage services over the internet or Direct Connect. DataSync can transfer your file system data and metadata, such as ownership, timestamps, and access permissions.

## How to migrate existing files to FSx for Lustre using AWS DataSync

You can use DataSync with FSx for Lustre file systems to perform one-time data migrations, periodically ingest data for distributed workloads, and schedule replication for data protection and recovery. For information about specific transfer scenarios, see [Where can I transfer my data with AWS DataSync?](https://docs.aws.amazon.com/datasync/latest/userguide/working-with-locations.html) in the *AWS DataSync User Guide*.

### Prerequisites

To migrate data into your FSx for Lustre setup, you need a server and network that meet the DataSync requirements. To learn more, see [Setting up with AWS DataSync](https://docs.aws.amazon.com/datasync/latest/userguide/requirements.html) in the *AWS DataSync User Guide*.
+ You have created a destination FSx for Lustre file system. For more information, see [Step 1: Create your FSx for Lustre file system](getting-started.md#getting-started-step1).
+ The source and destination file systems are connected in the same virtual private cloud (VPC). The source file system can be located on-premises or in another Amazon VPC, AWS account, or AWS Region, but it must be in a network peered with that of the destination file system using Amazon VPC Peering, Transit Gateway, AWS Direct Connect, or Site-to-Site VPN. For more information, see [What is VPC peering?](https://docs.aws.amazon.com/vpc/latest/peering/what-is-vpc-peering.html) in the *Amazon VPC Peering Guide*.
**Note**  
DataSync can only transfer across AWS accounts to or from FSx for Lustre if the other transfer location is Amazon S3.

### Basic steps for migrating files using DataSync

Transferring files from a source to a destination using DataSync involves the following basic steps:

1. Download and deploy an agent in your environment and activate it (not required if transferring between AWS services).

1. Create a source and destination location.

1. Create a task.

1. Run the task to transfer files from the source to the destination.
