In Cubase 6, is it possible to save as earlier version?

Hello, my friend is helping me with some editing of the drums. I use Cubase 6, while he has Cubase 4. Can I save the projects
as earlier versions of Cubase? I heard roomers this is possible…? But can´t work out how to do it… Thanks!

I have the same question but from Cubase 8.0 back to 7.5

I answered my own question. Cubase 7.5 just opened a Cubase 8.0 file no problem (without any ‘saving to earlier versions’) Excellent! Hope this helps you too Mollysilk!
