Cubase 10 Upgrade Question

I’m confused. Isn’t the trial version the full installer?

This is right off the page…

For the Cubase Pro trial version, you require a USB-eLicenser. If you don’t already own a USB-eLicenser, you can get one from the Steinberg Online Shop or from your local dealer.

Please notice: If you already have Cubase 10 or an earlier version installed, you will be required to re-install your version after the Cubase 10.5 trial period has expired and a permanent license for Cubase 10.5 hasn’t been activated. Please note that projects created or saved with Cubase 10.5 may not be fully compatible with Cubase 10.

So is this incorrect? I don’t want to have to install Cubase 7 all over again.
