Using a offline maps with old oruxmaps version

I have some offline maps witch I create with latest oruxmaps version 4.8.64. I want to use them in old version (4.4.1) on other device. I have copied files from one device to another. They are not loading: "Unable to open the map. Perhaps you need to update maps source". I updated the maps source, but this not helped. Is there any chance to use them? Thanks.
