Qlik Talend Administration Center Error Migrating Nexus OrientDB to PostgreSQL DB in Nexus Repository OSS

Lusemar_Oliveira · Jan 14, 2026 8:29:40 PM

For Talend Administration Center configured with Nexus, when attempting to migrate Sonatype Nexus Repository Manager OSS (versions prior to 3.77.0) from the embedded OrientDB database to an external PostgreSQL database, the Database Migrator utility may encounter the following error:

com.sonatype.nexus.db.migrator.exception.WrongNxrmEditionException:

Migration to an external database requires Nexus Repository Manager Pro and is not supported for Nexus Repository Manager OSS instances.

Resolution

To successfully migrate from OrientDB to PostgreSQL, follow the below migration paths recommended by Sonatype:

Migrating from OrientDB to H2 database (temporary step)

Use the Database Migrator utility to move your data from OrientDB into the embedded H2 database.

Documentation: Migrating from OrientDB to H2 database

Upgrade to Nexus Repository Community Edition (≥ 3.77.0)

PostgreSQL support is available only in Community Edition starting with version 3.77.0.

Documentation: Community Edition Onboarding

Migrating from H2 database to PostgreSQL database

Once upgraded, use the Database Migrator utility again to move from H2 into PostgreSQL.

Documentation: Migrating from H2 database to PostgreSQL database

Important Notes:

Migration is one‑way: once you move to PostgreSQL, you cannot revert back to OrientDB.

Ensure you have backups before starting any migration.

The migration process is managed by Sonatype’s Database Migrator utility and Qlik does not maintain or support this tool.

For issues with the migrator or Nexus Repository itself, contact Sonatype Support directly.

Cause

Nexus Repository OSS (3.70.4-02) does not support migration directly from OrientDB to PostgreSQL.

PostgreSQL support was introduced in the Community Edition starting with version 3.77.0.

Attempting to run the Database Migrator against OSS versions 3.70.4-02 results in the WrongNxrmEditionException.
