Dorico Upgrade from Version 1 to Version 2 in Switzerland

Hello, can someone please point me to the upgrade from 1 to 2?
A friend in Switzerland is thinking of staying on version 1…
He probably does not know what he is missing… so I would like to point him into the right direction…
Thank you for help.

You can buy the update by choosing Update from Dorico 1 from the list on the left-hand side on this page.

Thank you Daniel,
I suppose if one logs into that site from Switzerland the prices will be shown in Swiss Francs?

Yes, I believe so.
