I have a multicad structure that consists of both Catia V5 and Catia V6 data. I want to export the complete structure to catia V5. I have tried Export to catia file option and also Downward compatibility batch. Both does not work and fails with error - 3dexperience session consists of CATIA v5 data. Is there an option to export the multicad structure to CATIA V5 ? 

I am working on 3DExperience Cloud.
