IDF file to OSM -error with HVAC reversion

I am working on PNNL prototype buildings which include all idf files created according to from ASHRAE 90.1-2004 through 90.1-2013. First I got an error about version problem when I tried to import these idf files into Open Studio V2.2. I figured out how to update idf files and I updated them from their current version to EnergyPlus 8.7.0. Now I am trying to import these idf files to osm files but HVAC system does not come properly. I am getting error about fan, HVAC mainly related with energy systems. There is none problem about geometry, constructions, loads, thermal zones and schedules except HVAC. Do you have any idea how I can deal with this problem. Thanks
