Starting the Journey: Your Code and Existing Setup
Let's assume you currently have a JFrog repository containing your artifacts. Your JFrog configuration might look something like this:
# JFrog CLI configuration
JFROG_CLI_URL=https://your-jfrog-instance.com

This configuration allows you to interact with your JFrog instance using the JFrog CLI.
The Migration Process: Step-by-Step
- Prepare Nexus 3:
- Download and install Nexus 3 on your desired server.
- Configure your Nexus 3 instance. This includes setting up users, roles, and permissions.
- Create the necessary repositories within Nexus 3 to match your existing JFrog repositories.
- Export from JFrog:
- Use the JFrog CLI to export your artifacts from JFrog. This can be done individually or for entire repositories.
- For example, to export the "libs-release-local" repository, you would use:
jfrog rt dl --url $JFROG_CLI_URL --user $JFROG_CLI_USER --password $JFROG_CLI_PASSWORD libs-release-local
- Import to Nexus 3:
- Use the Nexus Repository Manager UI to import the exported artifacts into your newly created Nexus 3 repositories.

- Update CI/CD Pipelines:
- Adjust your build scripts and CI/CD pipelines to use the new Nexus 3 URLs and credentials.
- Test and Verify:
- Thoroughly test your deployment process and ensure everything is functioning correctly.
- Confirm that you can successfully retrieve artifacts from Nexus 3 and deploy them to your environments.
Key Considerations:
- Versioning: Carefully consider how to manage versioning during the migration process. It's best to maintain consistent versions between JFrog and Nexus 3.
- Dependencies: Ensure that all dependencies are migrated and configured correctly within your new Nexus 3 repositories.
- Access Control: Migrate existing user roles and permissions to ensure secure access to artifacts within Nexus 3.
