HMC Config Migrator (downloaded from https://launchpad.support.sap.com/#/notes/2333970) is unable to process HMC Tree nodes - fails with the following exception:
java.lang.NoSuchMethodError: com.hybris.cockpitng.config.explorertree.jaxb.ExplorerTree.getNavigationNodeOrTypeNode()Ljava/util/List;

Apparently the method of ExplorerTree. getNavigationNodeOrTypeNode() was renamed to getNavigationNodeOrTypeNodeOrDynamicNode()
