The following changes require manual actions (if applicable for your application):

  • MREF as labels are not allowed anymore. You should use template expressions. Please check: template expressions.

    • You can migrate the database first and if you encounter the following error

      Error:
      Conversion failure in entity type [#name#] attribute [#name#]; No converter found capable of converting from type [org.molgenis.data.support.DynamicEntity] to type [java.lang.String]

      You can fix these attributes in the Metadata Manager by editing the expression of the mentioned attribute.

  • If users or groups were giving special permissions on the Settings Manager Plugin, these permissions should be set again for the replacement Settings Plugin. The plugin itself is replaced automatically.
