Answer:
An RFEM 5 model can be opened in RFEM 6 which will transfer most of the geometry, materials, sections, and loading. There may be an exception to some elements for example, material databases which may have been updated or nonlinear support definitions that now have a different definition layout to name a couple. After selecting the file for import, a list of nontransferable elements will be presented before the model is opened in RFEM 6.
Add-on module data will not be available due to the program design changes between generations.
