-- How to use maps that were built in Datamapper v3.1.10. in Datamapper v3.1.9. ?
-- What are the procedures ?

* The Datamapper was implemented without any migration procedure from any version to any other. You can only manually move links (if the order was wrong in the previous maps), but if the you have a V1 map (non structural link), this can¿t be transformed into a structural link map. Only the rebuilding the map from scratch will be possible.
