Dear community,

I allow myself to ask you a question about top-down compatibility between 3DEXPERIENCE 2019 and 3DEXPERIENCE 2015 data and I hope that you will help me with the right answer.

 I’m wondering if we can open the 3DEXPERIENCE R2019 data in the older release  3DEXPERIENCE R2015. (I know that in the opposite way it already works) But, I'm not sure if Dassault Systèmes had already created a Top-down adaptation or compatibility between the two versions in the way that allows us to open the 3DX2019 data in the 3DX2015 version. 

Have someone the right answer, Please? 

Thank you 🙏 in advance.
