Data migration is a critical task for businesses looking to move data between different databases or platforms. This article provides a step-by-step guide on how to migrate data from Amazon Neptune, a graph database service, to PostgreSQL, a relational database service. We will use the AWS Neptune export service to export data in Turtle format (.ttl) to Amazon S3, and then use AWS Glue to transform and load the data into PostgreSQL.

Scenario

Let’s consider a simple example where we have data about users. Each user has a first name, last name, and email. We will export this data from Neptune, transform it, and load it into PostgreSQL.
