How to upgrade Cubase 11 to Cubase 13

Is there an upgrade path? Or do I need to purchase Cubase 13 in full?

Thanks for your assistance.

From Cubase Pro 11 to Cubase Pro 13?
That’s an update, not an upgrade.

yep you can go from 11 to 13, it just costs a little more than 12 to 13

That’s excellent as that’s what I’m looking for too.
Any link of info on how to do this?

Go to the Steinberg website, find the product you want to update, and hit the buy button.
