Automated Nexus 3 H2-to-PostgreSQL Migration Using Docker – My First Contribution

post by fer.bodijn on Jun 18, 2025

Hi all,

This is my first post here, so be gentle

I’ve created a Docker container to simplify running the Sonatype Nexus H2-to-PostgreSQL migrator, making it easier to test and use.

You can find the project here:

• GitHub - ferry/nexus-h2-to-psql-migrator: A containerized tool for migrating a Sonatype Nexus 3 H2 database to PostgreSQL

It includes:

• A Dockerfile
• Support for passing database parameters via environment variables
• The necessary jars for the Nexus migrator and H2 database tooling

Feedback and contributions are welcome!
