public class AddedDMRToTableDMRMigration
Before 1.5.0 a table domain model reference was simply a subclass of feature path domain model reference. This made
it impossible to use a different dmr to reach the multi reference. Starting with 1.5.0. it is possible to set a
different dmr leading to the multi reference on the table dmr. This migration creates a feature path dmr with the old
values on the table.
