# Migrating an existing graph to Amazon Neptune
<a name="migrating"></a>

There are a number of tools and techniques that can help you migrate existing graph data into Amazon Neptune from another data store.

A simple migration workflow involves the following steps:
+ Export the data from its existing store into Amazon Simple Storage Service (Amazon S3).
+ Clean and format it for import.
+ Load it into a Neptune DB cluster using [Neptune Bulk Loader](bulk-load.md).
+ Configure your Gremlin or SPARQL application to use the corresponding endpoint that Neptune provides.

**Note**  
Your Neptune cluster must be running in a VPC that your application can access.

There are ways to simplify and automate some of these steps, depending on where the data is stored:
