is it possible to convert or open the project file Newer version to an older version? (Revit 2021 to Revit 2020)

Hi @OmarBTP38K ,

Please take a look at this below link

https://knowledge.autodesk.com/support/revit/learn-explore/caas/sfdcarticles/sfdcarticles/Backwards-... 

In the above link, you will find one workflow to achieve the functionality you want.

1)Open the RVT/RFA file in the newer version of Revit.
2)Export to an IFC (only available for RVT files) or DWG. This export process converts the geometry in the file into a format that can be imported into the earlier version.
3)Open/Import the IFC or DWG into the older version of Revit.

I hope this helps.
