Migration Notes

Backward and Forward Compatibility

We do not guarantee forward compatibility for configuration, data or projects. I.e. importing a project created with DataIntegration v25.2.0 into DataIntegration v25.1.0 (or older) might not work.

Backward compatibility will be ensured or migration paths explained. I.e. projects created with DataIntegration v24.3.0 can be imported into DataIntegration v25.1.0.

Important info

Since v24.3.0, the components eccenca DataPlatform and eccenca DataManager are merged into a single component eccenca Explore.

eccenca DataIntegration

• The following plugins have been deprecated and will be removed in a future release:
  • Old Python plugins depending on Jython (Python 2.x)
  • Spark scripting plugins
  • Spark virtual dataset
  • Legacy REST operator
• To check if your instance uses any deprecated plugins, use the endpoint: GET {DataIntegrationURL}/api/core/usages/deprecatedPlugins
