There are separate upgrade fees for both RFEM 5 and the add-on modules that you currently own. The RFEM 5 upgrade fee is a set price while the add-on module upgrades vary.
There will only be one upgrade fee for multiple standards within the same material family. For example, if you currently own a seat of RF-STEEL AISC and RF-STEEL CSA, there is only one upgrade fee for both add-on modules, which you will now have access to steel design in RFEM 6 according to the AISC, CSA, EC3, and all other international standards. These add-ons now include all national and international standards in one product which will be much more cost effective.
