The best way of opening files created in newer versions in previous versions of WB is to write out the CDB file and then read it via External Model. Depending on how old the previous version is, some of the information will be lost. Generally, the mesh, the material assignments, and the connections come through but do not expect to import loads and boundary conditions. The import options for CDB files are improving significantly with every release.
