Move Cubase Project to another DAW

I’m about to switch over to “Studio One 3” or at least try it out.

So I need to move all my Cubase projects to Studio One. I found some info regarding this and apprantly they need to be exported as XML-files:

So is “File=>Export=>Music XML” the way to go here?

Just follow the directions on the page you linked, they look exactly correct. Make sure you read each word, though.
