Migration Notes¤


We do not guarantee forward compatibility for configuration, data or projects. I.e. importing a project created with DataIntegration v24.1.0 into DataIntegration v23.3.0 (or older) might not work.

Backward compatibility will be ensured or migration paths explained. I.e. projects created with DataIntegration v23.3.0 can be imported into DataIntegration v24.1.0.


There is a known issue and existing workaround with the new dependency port feature: you may receive a message like this when running your workflows:

Workflow Execution Error:
Not all workflow nodes were executed! Executed 2 of 7 nodes.

In this case, open the affected workflow in DataIntegration and click the save button once (no changes are required). After saving it will work again.


Migrate Default Graph Override¤

If the default workspace sets a exploreModuleConfiguration.defaultGraph but an additional workspace is configured to show graph lists, you might see the following error message:

Missing Graph configuration for Context. Please check that the graph
actually exists.

Previously, un-setting the exploreModuleConfiguration.defaultGraph of the default workspace required setting its value to the empty string "". The configuration now follows the standard pattern and expects an explicitly blocked value (i.e. setting it to null). All non-default workspaces that previously set the exploreModuleConfiguration.defaultGraph to the empty string "" need to be migrated by:

  1. Open the workspace in the (workspace) Configuration.
  2. Open Modules > Explore.
  3. Delete the empty "" value of defaultGraph by clicking on the icon.
  4. Click on the block button to set it to null.
  5. Save the workspace.


DP APIs do not return null values for unset fields anymore.


Check if null values of non mandatory fields are expected if you are using the DataPlatform APIs with a custom client.


No migrations are required going from cmemc 23.3.x to 24.1.x.
