Upgrade from Cubase 7 to Cubase 8 Pro

Can someone explain me step by step how to upgrade from Cubase 7 to Cubase 8 Pro?

Go to the Steinberg site

https://www.steinberg.net/en/shop/buy_product/product/cubase-pro-8.html

Choose Update from 7 or 7.5

Choose download

Download from the link given

Install

You don’t have to uninstall 7.5.

The update will pick up your preferences. However it might be a good idea to trash them and start again in 8 as many of us have had issues when importing projects - mostly minor stuff. You might want to locate where the mixer and insert presets are kept and import them by placing them in the corresponding folders in the event - however they should be updated too.

Good luck
