Migration Notes¤


We do not guarantee forward compatibility for configuration, data or projects. I.e. importing a project created with DataIntegration v23.2 into DataIntegration v23.1 (or older) might not work.

Backward compatibility will be ensured or migration paths explained. I.e. projects created with DataIntegration v23.1 can be imported into DataIntegration v23.2.


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.


Due to the removal of the authorization.abox.prefix configuration option, a change in your setup may be required.


Even if you have not changed this value (to anything other than, please remove the authorization.abox.prefix configuration property from your DataPlatform application.yml. This property must be absent or DataPlatform will not start.

From v23.3 AccessConditions are only regarded if their IRIs use the prefix (e.g. have an IRI like Required action:

  • If you have been using a different prefix for your AccessConditions, change the prefix of these resources. E.g. by:
    • search / replace the old prefix with the new one in your RDF graph backup
    • using a SPARQL query like:

      PREFIX eccauth: <>
      INSERT {
          GRAPH <urn:elds-backend-access-conditions-graph> {
              ?new_acl a eccauth:AccessCondition .
              ?new_acl ?p ?o .
      WHERE {
          # this Graph IRI corresponds to your `authorization.abox.accessConditions.graph` configuration
          # default <urn:elds-backend-access-conditions-graph>
          GRAPH <urn:your-custom-namespace> {
              ?acl a eccauth:AccessCondition .
              ?acl ?p ?o .
              BIND(IRI(REPLACE(STR(?acl), "urn:your-custom-prefix", "")) AS ?new_acl)
      } ;

Update of client-authentication-method property needed

Due to an upgrade of the spring boot library the client-authentication-method property needs to be chaged to client_secret_basic in your DataPlatform application.yml: client_secret_basic

(was basic which is not working anymore)


  • The upgrade to click v8 involves new completion functions (see completion manual)
    • Old: _CMEMC_COMPLETE=source_zsh cmemc
    • New: _CMEMC_COMPLETE=zsh_source cmemc
