Migration process

If you’re upgrading from an older version of Obeo Enterprise for SysON to the latest release, this section provides step-by-step guidance on migrating your existing data and settings to the new version.

In any case, it is strongly recommended to back up your data before proceeding with any migration.

1. 2026.9.0

Liquibase 5 has switched from the Apache License v2.0 to the Functional Source License (FSL). As a result, future versions of Liquibase cannot be used directly in Obeo Enterprise for SysON, because the FSL is not an approved license for third-party dependencies at the Eclipse Foundation. Obeo Enterprise for SysON 2026.9.0 downgrades Liquibase from 5.0.3 to 4.33.0. Our tests show that the downgrade to 4.33.0 does not break Obeo Enterprise for SysON; we will continue to monitor future Liquibase releases.

Before upgrading to 2026.9.0, download all models and projects and back up your database.
