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 v26.1.0 into DataIntegration v25.3.0 (or older) might not work.

Backward compatibility will be ensured or migration paths explained. I.e. projects created with DataIntegration v25.3.0 can be imported into DataIntegration v26.1.0.

Important info

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

eccenca DataIntegration¤

  • The dataset parameter Clear before execution is now deprecated, moved to the advanced section, and defaults to false. Review workflows or templates that relied on the previous default behavior.

Breaking Change Pre-Announcement

Changes to DataIntegration container configuration mount points will be rolled out with the next release, v26.2. We are harmonizing configuration paths under a single central entry point to simplify configuration.

Details will be provided as part of the helm and docker-compose deployment templates.

Please read the migration notes carefully.

eccenca Explore¤

  • Custom navigation queries need to be adjusted manually.
  • Existing workspaces require a workspace configuration migration to introduce the new workspace configuration versioning description field.

cmemc¤

v26.1.0 of cmemc removes the following deprecated functionality:

  • dataset resource command group
    • Deprecated in v25.6.0. Use the project file command group instead.
  • graph tree command
    • Deprecated in v25.2.0. Use the graph imports tree command instead.
  • admin store migrate command
    • Deprecated in v25.0.0. Use the admin migration command group instead.
  • --overwrite options
    • Deprecated in v25.0.0. Use the --replace option instead.
    • Affected commands: admin store export, project import, project export, admin workspace export
  • Removed deprecated auto-completion URIs.
  • dataset delete command
    • The --project option was removed. Use --filter project XXX instead.
  • Removed the project create --from-transformation option.
